Assam Police has constituted a Special Investigation Team (SIT) to probe the death of Bir Lachit Sena leader Manasjyoti Chetia in Sivasagar, authorities confirmed on 27 August. The SIT has been formed by Sivasagar Police and is tasked with establishing the full circumstances surrounding the incident that led to Chetia's death.
How Chetia Died
Chetia died on 25 August, two days after an incident reported on 23 August. He had been receiving medical treatment for injuries sustained in that incident before succumbing. The precise nature of the 23 August incident is under active investigation, with authorities working to determine its direct connection to his death.
SIT Composition and Mandate
The SIT is headed by Sivasagar Deputy Superintendent of Police Lila Bora. The team also includes Amguri Police Station Officer-in-Charge Mridul Hazarika and Nazira Police Station Second Officer SI (UB) Siraj Saikia, who has been designated as the Investigating Officer. Nazira Police Station WSI (UB) Sumi Barman is also part of the team.
The SIT has been directed to examine available evidence, record witness statements, and reconstruct the sequence of events preceding the incident. It will also assess whether the evidence supports the allegations made in the complaint filed by the Bir Lachit Sena.
Five Detained in Connection With the Case
Police have detained five individuals named in the complaint lodged by the Bir Lachit Sena. The SIT will examine the role, if any, of these detainees in connection with Chetia's death. Whether criminal liability arises from the incident will depend on the probe's findings.
What Happens Next
Investigators are expected to ascertain whether the 23 August incident directly caused Chetia's subsequent death on 25 August. Further action — including any formal charges — will be determined by the evidence gathered by the investigating team. The formation of a dedicated SIT signals that authorities are treating this as a matter requiring focused, structured inquiry.
Point of View
Named after the Ahom general, carries symbolic weight in Assam's identity politics. The two-day gap between the reported incident and Chetia's death will be the crux of the probe: establishing that causal link is what converts an investigation into a prosecution. Five detentions made early suggest police had enough prima facie material to act, but the SIT's findings will determine whether those detentions hold. Assam has seen repeated scrutiny of how organisations with ethno-cultural identities are treated by the state apparatus — this case will be watched closely on that count.
