The Assam Police’s Special Task Force (STF) recently carried out a major crackdown by arresting 11 people suspected of having ties to an extremist group. These individuals are linked to Imam Mahmuder Kafila (IMK), a Bangladesh-based organisation that grew out of the banned Jamaat-ul-Mujahideen Bangladesh (JMB).
Security forces raided multiple locations in Assam and Tripura on Dec 29-30, arresting 11 suspects from the Imam Mahmuder Kafila (IMK), a JMB offshoot propagating Ghazwatul Hind ideology via encrypted "Purva Akash" groups.

The arrests took place during late-night raids on the 29th and 30th of December across four districts in Assam, Barpeta, Baksa, Chirang, and Darrang, as well as in West Tripura.
Among those caught in Assam were ten men: Nasim Uddin, Junab Ali, Afrahim Hussain, Mizanur Rehman, Sultan Mehmud, Md Siddique Ali, Rasidul Alam, Mahibul Khan, Sharuk Hussain, and Md Dilbar Razak. Another man, Jagir Miah, was arrested in West Tripura.
According to the police, the group has become much more active since the government change in Bangladesh in August 2024. The STF chief, Partha Sarathi Mahanta, explained that the group had set up a specific cell in Assam, run by a leader in Barpeta and coordinated by two Bangladeshi nationals known as Umar and Khalid. The head of the Assam cell of IMK is identified as Nasim Uddin alias Tamim of Barpeta Road, Assam.
IMK was founded by Jewel Mahmud, alias Imam Mahmud Habibullah alias Sohail, a former member of JMB who claims to be the Amir of IMK and propagates the ideology of “Ghazwatul Hind”. As per the police, following the regime change in Bangladesh in August 2024, Senior Leaders of JMB, Ansarullah Bangla Team (ABT) and Al-Qaeda in the Indian Subcontinent (AQIS) issued directions to IMK Leadership to activate and expand its Indian Modules. For this, Bangladeshi Nationals Umar and Khalid were assigned to coordinate Assam-based activities.

The way this group operates is quite modern but secretive. They used encrypted social media apps to talk and find new members. One such social media group is titled ‘Purva Akash’, which functions as a Principal Communication and Recruitment Platform. Police found that they targeted people in Assam, West Bengal, and Tripura, focusing on radicalising them and raising money.
The IMK projects itself as a Ghazwatul Hind-Centric Extremist Module and propagates an ideology aligned with Proscribed Transnational Jihadi Organisations. The group spreads extremist propaganda advocating violent Jihad and the armed conquest of India through Digital Platforms, including dedicated Websites and social Media platforms under the Ghazwatul Hind banner. Assam police said that radical Literature authored by IMK Leadership, including ‘Sarbobhoumo ‘Khamatar Malik Allah’ and ‘Ghazwatul Hind er Sonkhipto Alochona’, is systematically circulated to indoctrinate Cadres and sympathisers through Online Platforms.
Some of the people involved already had Indian passports and had travelled to Bangladesh before, while others were former members of banned terror groups. The process started online, where they would find people through “online Jihadist channels” and feed them IMK propaganda.
Assam Police stated that the group started using local mosques and religious gatherings to hold secret meetings since December 2024. At a meeting in Barpeta on 28th December 2024, leaders openly talked about starting an armed struggle in India. These small meetings were designed to brainwash local youth and get them ready for violence. Even the violent ideas were openly promoted.
Some recruits even went to Bangladesh on legal visas to meet top leaders, and many were told to take their families and go there for weapons training. In April 2025, two operatives from Assam even went to Meghalaya to meet their Bangladeshi handlers. The police believe this constant cross-border movement is a serious threat to the country’s safety.
