Dibrugarh Police have arrested six people, including senior leaders of the Upper Assam-based organisation Bir Lachit Sena and two other regional socio-political groups, in connection with the kidnapping and extortion of an official from a contractor firm working for Oil India Limited (OIL) in Duliajan. The case has escalated into a broader political and legal confrontation, with Assam Chief Minister Himanta Biswa Sarma saying the state government is weighing a ban on Bir Lachit Sena over what he described as a pattern of extortion and violence, comparing the potential action to bans previously imposed on the insurgent group ULFA. The organisation has, in turn, publicly disputed the fairness of the crackdown, alleging one of its arrested members is politically connected to Assam's ruling party, an accusation that led police to detain the organisation's own spokesperson mid-press-conference.
Background
The case originates from a complaint filed by Uttam Jyoti Bora, an official of Udipta Energy and Equipment Private Limited, a contractor engaged by OIL at its Duliajan field headquarters in Dibrugarh district. Bora alleged that on the night of 10 May 2026, a group of individuals forcibly entered the company's office, created a hostile situation, disrupted operations, physically assaulted staff, and abducted him in a vehicle while demanding extortion money. That specific sequence of alleged events — forced entry, disruption of routine business operations, physical assault, and abduction with a cash demand — forms the factual basis prosecutors will need to establish against each named accused individually as the case proceeds to trial.
Dibrugarh Police made an initial round of four arrests in the case on 14 June 2026, identifying the accused as Rintu Dutta, president of Bir Lachit Sena's Dibrugarh unit; Kankan Rajkonwar, president of the Tai Ahom Students' Union in Duliajan; Binod Kumar Sonowal, president of the Sonowal Kachari Yuba Mancha in Duliajan; and Manas Pratim Gohain, secretary of Bir Lachit Sena's Duliajan unit. Police subsequently registered two FIRs at Duliajan Police Station and, by early August, had arrested six people in total in connection with the case, with investigators indicating further arrests remained possible as they traced additional links in what they describe as a wider extortion network. That the accused span three separate organisations — not Bir Lachit Sena alone — also complicates any narrative that frames this purely as a single-organisation problem, since the Tai Ahom Students' Union and the Sonowal Kachari Yuba Mancha, both community and identity-based bodies representing specific Assamese ethnic groups, are implicated in the same case alongside Bir Lachit Sena, even though only the latter has so far been singled out publicly for a possible ban. Whether that selective focus reflects a genuine assessment that Bir Lachit Sena's conduct is qualitatively more severe or more sustained than that of the other two organisations, or simply that it has been the more visible and vocal of the three in public commentary, is not something the available reporting resolves, and is worth watching as the case develops further.
Key Details
- Incident date: 10 May 2026, at the Duliajan office of OIL contractor firm Udipta Energy and Equipment Private Limited.
- Complainant: Uttam Jyoti Bora, a company official who alleged he was assaulted, abducted and extorted.
- First arrests: four individuals arrested 14 June 2026, drawn from three separate regional organisations — Bir Lachit Sena, the Tai Ahom Students' Union, and the Sonowal Kachari Yuba Mancha.
- Total arrests as of early August: six people, following two FIRs registered at Duliajan Police Station.
- Police statement: Additional Superintendent of Police Atul Kumar confirmed, "We have so far arrested six persons in connection with two FIRs registered at Duliajan Police Station."
- CM's characterisation: Chief Minister Sarma said, "We are very unhappy with the activities of [Bir] Lachit Sena. Like ULFA, we might have [to consider a ban]," and separately stated that "in the last two months, they have destroyed the atmosphere of business" in the areas where the group is active.
- Organisation's defence: Bir Lachit Sena's state general secretary pushed back publicly, claiming one of the arrested individuals is "a member of the ruling BJP and very close to many senior leaders," implying selective or politically inconsistent treatment of the case.
- Notable escalation: police reportedly detained the Bir Lachit Sena spokesperson making that claim during his own press conference addressing the arrests, without immediate comment from authorities on the detention itself.
Not an Isolated Case: The October 2025 Guwahati Kidnapping
The Duliajan case is not the first time Bir Lachit Sena members have faced extortion and kidnapping allegations. In October 2025, Guwahati Police arrested eight people for allegedly kidnapping a businessman for ransom, with five of the arrested individuals identified as members of Bir Lachit Sena. The kidnappers had reportedly demanded a ransom of ₹15-20 lakh for the victim's release before he was rescued by police. Guwahati Police officials alleged at the time that the organisation was running a systematic extortion network targeting businessmen through intimidation and violence, an allegation the Duliajan case has now amplified with a second, geographically distinct incident involving different named leaders. That the two cases occurred in different districts — Guwahati in October 2025, Duliajan in Dibrugarh district in May 2026 — and involved different named individuals within the organisation is significant for how prosecutors and the state government are likely to frame any eventual ban case: a pattern spanning multiple districts and incidents is a materially stronger basis for arguing organisational, rather than purely individual, culpability than a single isolated case would be.
Separately, a former Bir Lachit Sena leader, Bikash Axom, has also been remanded to police custody in an unrelated case, adding to a broader pattern of legal action against individuals associated with the organisation across different districts and time periods, rather than the Duliajan case standing alone as a single, isolated incident. Media reports have also referenced allegations of hate speech connected to the organisation alongside the extortion and kidnapping cases, suggesting the government's concerns, and any eventual ban case, may not rest solely on financial crime allegations but on a broader combination of conduct the state considers threatening to public order. That broader framing matters for how any eventual UAPA referral would be argued: financial crime alone is not typically sufficient grounds for an unlawful-association declaration under the Act, which is oriented toward activity threatening India's sovereignty, integrity or public order more directly, meaning the government's case would likely need to lean on the combination of extortion, violence and any hate-speech allegations together, rather than the extortion allegations in isolation.
At a Glance: Case Timeline
| Date | Development |
|---|---|
| 10 May 2026 | Alleged kidnapping, assault and extortion at Duliajan OIL contractor office |
| 14 June 2026 | Four organisation leaders arrested |
| Early August 2026 | Total arrests reach six across two FIRs; CM signals possible ban on Bir Lachit Sena |
The roughly three-month span between the original incident and the state government publicly weighing an organisational ban indicates this case has evolved from a single criminal complaint into a broader policy question about how Assam treats regional socio-political outfits accused of using extortion and intimidation tactics against businesses operating in areas where they hold local influence. That evolution — from a single FIR to a live debate about proscribing an entire organisation — is itself a useful marker of how quickly a criminal case involving named organisational leadership can escalate into a matter of state policy when the accused hold formal positions within recognisable regional bodies, rather than acting as unaffiliated individuals with no organisational identity attached to their alleged conduct.
Local Impact
For businesses and contractors operating in Duliajan and the wider Upper Assam oil belt, a case of this kind, involving named leaders of locally influential organisations allegedly using intimidation and abduction to extract money from a company working with a major public-sector oil operator, raises direct concerns about the operating environment for legitimate commercial activity in the region. Oil India Limited's Duliajan operations sit at the centre of Assam's oil and gas economy, and CM Sarma's comment that such activity has "destroyed the atmosphere of business" reflects a concern that goes beyond this single case to the broader investment climate in areas where regional organisations of this kind operate with local social and political standing. Oil and gas sector operations in Upper Assam, given their fixed physical infrastructure and inability to simply relocate away from a district where intimidation problems arise, are particularly exposed to this kind of local extortion risk compared with more mobile industries, which is part of why a case touching an OIL contractor specifically has drawn attention beyond what a similar complaint against an unrelated small business might have received.
For members and supporters of Bir Lachit Sena and the other named organisations implicated in the case, a potential state ban carries significant consequences well beyond whatever penalties the individual criminal cases already filed might eventually produce: banned organisations in India typically face restrictions on organising, fundraising and public activity under laws such as the Unlawful Activities (Prevention) Act, the same broad legal framework historically used against insurgent groups like ULFA, meaning the comparison CM Sarma drew is not merely rhetorical but points toward a specific, more severe category of legal action than ordinary criminal prosecution of individual members. That said, formal proscription proceedings under UAPA generally require the state to compile and submit a detailed dossier of evidence to the central Ministry of Home Affairs, followed by review, before any notification takes effect, meaning members and affiliated individuals of Bir Lachit Sena face no immediate change in the organisation's legal status even as the political rhetoric around a ban intensifies.
What a Ban Would Actually Mean: The ULFA Precedent
Chief Minister Sarma's comparison to ULFA, the United Liberation Front of Asom, points to a specific and well-documented legal history. ULFA, formed in 1979 seeking Assam's secession from India through armed struggle, was first banned in 1990 and has had that ban periodically renewed since, most recently extended by five years, under Section 35 of the Unlawful Activities (Prevention) Act (UAPA), 1967, which empowers the government to declare an organisation "unlawful" if it engages in activities promoting terrorism, secession or comparable threats to India's sovereignty and integrity. The Ministry of Home Affairs has, in the past, also constituted a formal tribunal specifically to examine and review ULFA's banned status, a legally mandated review process UAPA bans are subject to periodically rather than being permanent by default. That tribunal mechanism exists specifically because UAPA requires periodic judicial review of unlawful-association declarations rather than allowing an indefinite ban to stand unchallenged, a procedural safeguard that would presumably apply to any eventual ban on Bir Lachit Sena in the same way it has applied to ULFA's status over multiple renewal cycles since 1990.
One important distinction is worth noting: declaring an organisation "unlawful" under UAPA is, in practice, a central government power exercised through the Ministry of Home Affairs, not something a state government can unilaterally impose on its own authority. If Assam's government wishes to see Bir Lachit Sena formally banned under the same legal framework used against ULFA, that would in practice require building a case and referring the matter to the central government, rather than the state notifying a ban independently — making CM Sarma's public comparison a signal of political intent and pressure at this stage, rather than confirmation that a state-level ban mechanism is imminently available.
What Happens Next
The criminal case against the six, and potentially more, arrested individuals will proceed through Dibrugarh's court system on charges related to kidnapping, assault and extortion, while investigators have signalled the inquiry into the alleged wider extortion network remains active and could produce further arrests. That open-ended framing — police describing an active, ongoing investigation into a network rather than a closed case with a fixed number of accused — typically signals that authorities believe the individuals already arrested are not the full extent of those involved, whether as direct participants in the Duliajan incident or as part of a wider financial or organisational structure supporting the alleged extortion activity. Separately, and on a different track, any formal move to ban Bir Lachit Sena would require the state government to build a documented case for outlawing the organisation under relevant law, a process that typically takes longer and faces a higher evidentiary bar than prosecuting individual members for a specific alleged crime.
Bir Lachit Sena's public counter-allegation, that one arrested individual has close ties to the ruling BJP, and the subsequent detention of its own spokesperson while making that claim publicly, are likely to keep the case politically contentious regardless of how the underlying criminal prosecution itself proceeds through the courts, with opposition parties and civil liberties observers likely to watch closely whether the state's response to Bir Lachit Sena is applied consistently to other regional organisations accused of similar conduct. Assam is home to a range of similar regional socio-political and identity-based organisations beyond Bir Lachit Sena, and how the state calibrates its response — individual prosecutions versus organisational bans, and against which specific groups — is likely to be read as a signal of broader state policy toward this category of organisation, not simply a response to one company's complaint in one district.
Frequently Asked Questions
What happened in the Duliajan extortion case?
On 10 May 2026, a group allegedly forcibly entered the Duliajan office of an OIL contractor firm, assaulted staff, abducted an official, and demanded extortion money, according to a complaint filed by company official Uttam Jyoti Bora.
Who has been arrested in connection with the case?
Six people have been arrested in total, including Rintu Dutta and Manas Pratim Gohain of Bir Lachit Sena, Kankan Rajkonwar of the Tai Ahom Students' Union, and Binod Kumar Sonowal of the Sonowal Kachari Yuba Mancha.
What is Bir Lachit Sena?
Bir Lachit Sena is an Upper Assam-based socio-political organisation that has, at times, resorted to confrontational tactics in its activities, particularly around issues related to suspected infiltration, and now faces allegations of running a systematic extortion network.
Is Assam planning to ban Bir Lachit Sena?
Chief Minister Himanta Biswa Sarma has said the state government is considering a ban on the organisation, comparing the potential action to bans previously imposed on the insurgent group ULFA, though no formal ban has been announced.
What did Bir Lachit Sena say in response to the arrests?
The organisation's state general secretary claimed one of the arrested individuals is a member of the ruling BJP with close ties to senior leaders, suggesting the case reflects selective treatment; police subsequently detained the spokesperson during his press conference making that claim.
What law would be used to ban an organisation like Bir Lachit Sena?
Bans on organisations in India, including past bans on insurgent groups like ULFA, are typically imposed under laws such as the Unlawful Activities (Prevention) Act, which restricts a banned group's ability to organise, fundraise and operate publicly.
Where is Duliajan and why does this case matter to Assam's economy?
Duliajan, in Dibrugarh district, is a major hub for Oil India Limited's operations and sits at the centre of Assam's oil and gas economy, making extortion allegations targeting a contractor there a concern for the region's broader business investment climate.
Has Bir Lachit Sena faced similar allegations before?
Yes. In October 2025, Guwahati Police arrested eight people, five identified as Bir Lachit Sena members, for allegedly kidnapping a businessman and demanding a Rs 15-20 lakh ransom, an incident officials cited as evidence of a broader extortion pattern.
What is ULFA and why is it relevant to this case?
ULFA, the United Liberation Front of Asom, is an armed insurgent group formed in 1979 seeking Assam's secession from India, first banned in 1990 under the Unlawful Activities (Prevention) Act and periodically re-banned since; CM Sarma invoked it as a comparison for the severity of legal action being considered against Bir Lachit Sena.
Can a state government ban an organisation under UAPA on its own?
No. Declaring an organisation unlawful under UAPA is a central government power exercised through the Ministry of Home Affairs, meaning Assam would need to refer the matter to the Centre rather than imposing a ban independently.
For now, the most concrete, verifiable facts remain the ones already before the courts: six people arrested, two FIRs registered, and a criminal case that will be decided on evidence presented in Dibrugarh, regardless of how the surrounding political debate over a potential ban ultimately resolves.
North East Connect will continue tracking developments in both the criminal case and any formal steps the state government takes toward pursuing a ban on Bir Lachit Sena.
Whether critics view the spokesperson's detention as a proportionate response to disruptive conduct at a press event or as a heavy-handed attempt to silence public criticism of the police investigation is, at this stage, a matter of interpretation rather than settled fact, since neither police nor the organisation has offered a full public account of exactly what transpired at that press conference.
A single office in Duliajan, one alleged night of abduction and assault in May, has now travelled a long distance: to a Chief Minister invoking the name of a banned insurgency, to a spokesperson detained mid-sentence, and to a genuine open question about where Assam draws the line between a socio-political organisation and an unlawful one.
None of that legal complexity changes what is already established fact: six people arrested, two FIRs filed, one Chief Minister publicly weighing an unprecedented step, and one organisation loudly disputing every part of that account.
The rest, for now, is claim and counterclaim, waiting on a court and, potentially, a central ministry to sort out.
What began as one company's police complaint has become a live test of how Assam intends to handle organisations that sit somewhere between civic activism and outright criminal enterprise.
The next public hearing date, and any formal referral to New Delhi, will tell us which direction this case is actually heading.
