Guwahati : The National Investigation Agency (NIA) has filed a chargesheet against 11 individuals accused of conspiring to expand the network of a banned terror outfit across Assam, Tripura, West Bengal and other parts of the Northeast.

The chargesheet was submitted before the NIA Special Court in Guwahati on Friday under provisions of the Bharatiya Nyaya Sanhita (BNS), 2023, and the Unlawful Activities (Prevention) Act (UAPA), 1967, in connection with an alleged conspiracy linked to an offshoot of the banned Jama’atul Mujahideen Bangladesh (JMB).

According to the NIA, investigations revealed that the accused were associated with Imam Mahmuder Kafila (IMK), an organisation allegedly formed by senior JMB operative Imam Mahmud Habibullah to further the activities of the proscribed outfit in India.

The agency alleged that the group was working to spread JMB’s extremist ideology by radicalising vulnerable youths, expanding its organisational network and disseminating anti-India propaganda across West Bengal and several northeastern states.

Investigators claim that the accused conducted secret meetings, organised religious indoctrination sessions, circulated extremist materials and used digital platforms to recruit new members and encourage allegiance to the leadership of both IMK and JMB.

Among those named in the chargesheet, Nasimuddin has been identified as the alleged head of IMK’s operations in Assam, while Jagir Mia is accused of leading the outfit’s activities in Tripura.

The NIA said its probe uncovered evidence suggesting coordinated efforts to strengthen the organisation’s presence in the region. During searches and investigations, officials reportedly seized documents, electronic devices and digital records that the agency claims support the allegations outlined in the chargesheet.

The case is part of the NIA’s broader efforts to identify and dismantle extremist networks operating within the country and prevent the spread of radical ideologies. Officials said the investigation focused on the alleged attempts by the accused to recruit supporters and build organisational infrastructure for the banned group.

With the filing of the chargesheet, the matter will now proceed through the judicial process, where the allegations made by the NIA will be examined and tested in court. The accused are presumed innocent unless proven guilty through due process of law.

The development comes amid continued efforts by security agencies to monitor and counter extremist activities in the Northeast and eastern India, regions that have remained under close surveillance due to concerns over cross-border terror links and radicalisation networks.
