The NIA has filed a chargesheet against 11 accused, including Tripura IMK chief Jagir Mia and Assam operative Nasimuddin, for allegedly promoting terrorist ideology, radicalising vulnerable youth, expanding IMK/JMB networks, and spreading anti-India propaganda across Tripura, Assam, West Bengal, and Northeast India.
The National Investigation Agency (NIA) has filed a chargesheet against 11 accused, including the alleged head of the Tripura unit of Imam Mahmuder Kafila (IMK), an alleged offshoot of the banned Jamaat-ul-Mujahideen Bangladesh (JMB), in connection with an alleged terror conspiracy aimed at spreading extremist ideology across northeastern India and West Bengal.
According to officials, the chargesheet was submitted before the NIA Special Court in Guwahati after an extensive investigation into the activities of the organisation. Among those named are Jagir Mia, also known as Jagir Ali, who is alleged to have led IMK operations in Tripura, and Nasimuddin, who is accused of heading the outfit’s activities in Assam.
The case relates to an alleged conspiracy by IMK, which investigators describe as an offshoot established to further the objectives of the proscribed Bangladesh-based terrorist organisation Jamaat-ul-Mujahideen Bangladesh (JMB) within India. The NIA has alleged that the accused worked together to expand the organisation’s presence in Tripura, Assam, West Bengal and other northeastern states through recruitment, radicalisation and dissemination of extremist propaganda.
Jagir Mia, son of Hanif Mia, was arrested on December 30 last year during a coordinated operation conducted by Tripura Police, Assam Police and other security agencies. The operation was carried out in Joypur under the West Agartala Police Station jurisdiction following intelligence inputs gathered during a nationwide security operation.
Officials stated that the arrest was part of a larger counter-terrorism effort involving multiple law enforcement and intelligence agencies working together to dismantle extremist networks operating across state boundaries.
According to the NIA, investigations revealed that the accused allegedly sought to radicalise vulnerable youth, recruit new members and strengthen the organisational network of IMK within India. The agency further alleged that digital platforms, clandestine meetings, religious indoctrination programmes and circulation of extremist literature were used to promote anti-India propaganda and encourage allegiance to the leadership of IMK and JMB.
The investigation further claims that senior JMB member Imam Mahmud Habibullah established Imam Mahmuder Kafila (IMK) to advance the banned outfit’s activities on Indian soil. The NIA alleges that IMK functioned as a platform to expand extremist influence while attempting to build an organised support network across several states.
Investigators said the accused allegedly held secret meetings to coordinate organisational activities and identify potential recruits. The agency further claims that these meetings were complemented by religious indoctrination sessions designed to influence susceptible individuals and encourage support for the organisation’s ideology.
During the course of the investigation, the NIA reported recovering several incriminating documents, electronic devices and digital records. According to investigators, these materials form a significant part of the evidence supporting the charges against the accused. Digital forensic analysis and documentary evidence are expected to play an important role during judicial proceedings.
The agency has maintained that the conspiracy extended beyond physical meetings, with extensive use of digital communication platforms for propaganda dissemination, recruitment and coordination. Investigators allege that the accused actively promoted extremist content online while attempting to expand the reach of the organisation across multiple regions.
Among the chargesheeted accused, Nasimuddin has been identified as the alleged head of IMK’s operations in Assam, while Jagir Mia is accused of overseeing the outfit’s activities in Tripura. The NIA contends that both played significant roles in strengthening the organisation’s presence and coordinating its alleged operations within their respective states.
The filing of the chargesheet marks a significant milestone in the investigation, though it is important to note that the allegations contained in the chargesheet remain subject to judicial scrutiny. The accused are entitled to due process under law, and their guilt or innocence will ultimately be determined by the competent court based on the evidence presented during trial.

The NIA has stated that efforts to identify additional links and prevent the spread of extremist ideology will continue as part of its broader counter-terrorism operations across India.
