The Indian Army detained Nanda Mandal, a Bangladeshi national employed as a civilian laborer at the Bengdubi military station near Siliguri, West Bengal, on November 5, 2025, during a routine security reverification drive. The man was found carrying a Bangladesh national identity card alongside multiple Indian identity documents, including an Aadhaar card, PAN card, and voter ID, all procured through fraudulent means. This discovery at the strategically sensitive Bengdubi station, close to the crucial Siliguri Corridor or “Chicken’s Neck” that connects mainland India to the northeastern states, raised serious national security concerns. The Army immediately handed Mandal over to local police for investigation, who revealed that he had illegally entered India in 1990 and had been living in Jalpaiguri. This case highlights the persistent issue of Bangladeshi nationals illegally obtaining Indian documents to secure employment within the country and poses significant risks of infiltration in sensitive military installations. Authorities have intensified verification measures and collaboration between military intelligence and law enforcement to prevent further security breaches at critical border regions. This incident also renews focus on the challenges of illegal immigration and document fraud along India’s eastern frontier.
