NIA arrests 15th accused in JMB-linked terror plot targeting Bengal, Northeast
Synopsis
Key Takeaways
The National Investigation Agency (NIA) on Sunday, 11 October 2026, arrested one more accused from West Bengal in connection with a terror conspiracy linked to Imam Mahmuder Kafila (IMK), a proscribed offshoot of the banned Bangladeshi terrorist organisation Jamaat-ul-Mujahideen Bangladesh (JMB). The arrest brings the total number of accused apprehended in the case to at least 15, as investigators continue to unravel what officials describe as a wide-ranging plot to expand extremist networks across West Bengal and India's north-eastern states.
Several digital devices — including mobile phones and memory cards — were seized from the accused at the time of arrest, the NIA said in an official statement.
Background and Earlier Arrests
The latest detention follows a major enforcement action on 29 September, when the NIA arrested 13 accused persons after conducting simultaneous searches at 16 locations across Assam, West Bengal, and Kerala. Prior to that, on 25 June, the agency filed a chargesheet against 11 accused before the NIA Special Court in Guwahati, Assam, invoking provisions of the Bharatiya Nyaya Sanhita (BNS), 2023, and the Unlawful Activities (Prevention) Act (UAPA), 1967. The investigation is registered as case RC-01/2026/NIA/GUW.
What the Conspiracy Involved
According to the NIA, Imam Mahmud Habibullah, identified as a senior member of JMB, established IMK with the explicit objective of advancing the banned organisation's agenda within India. Investigators allege that the accused operated through clandestine meetings, religious indoctrination programmes, and the circulation of extremist literature to radicalise vulnerable youth and recruit them into the network.
Digital platforms — notably Telegram — were reportedly misused to spread anti-India propaganda and disseminate extremist ideology. The accused also allegedly worked to foster loyalty to IMK/JMB leadership and systematically strengthen the outfit's presence across the eastern and north-eastern regions of India, according to the agency's statement.
Strategic Significance of the Target States
The focus on West Bengal and the Northeast is notable. These states share India's eastern border with Bangladesh, making them historically sensitive to cross-border extremist infiltration. JMB, which was behind the deadly 2005 serial blasts in Bangladesh, has been banned in India, yet its offshoots have periodically attempted to establish a foothold on the Indian side. This is among the most significant enforcement actions against a JMB-linked network in recent years, involving multiple states and a sprawling digital trail.
Investigation Status and What Comes Next
The NIA has stated that further investigation is ongoing to establish the full extent of the conspiracy and identify any remaining associates. Analysts tracking Islamist extremism in South Asia note that the use of encrypted messaging apps for recruitment and radicalisation has become a recurring challenge for security agencies across the region. With chargesheets already filed and more arrests possible, the case is expected to proceed through the NIA Special Court system over the coming months.
