Thane: Thane Police Commissioner arrested 227 Bangladeshi nationals in 2025, as authorities stepped up crackdown on illegal immigrants living in the city without valid documentation. According to data from the Thane city police, last year they registered 116 cases against undocumented Bangladeshi citizens and solved each and every one of them, achieving a 100% detection rate. “The figures indicate a sharp escalation in law enforcement which officials say is driven by growing concerns over national security and local law and order,” Thane Police Commissioner Ashutosh Dumbre said.The crackdown gained new momentum following a high-profile incident in which a previously detained illegal immigrant was linked to the attack on a Bollywood actor. The case highlighted the issue of undocumented residents and prompted increased surveillance at all police stations in the precinct.Dumbre has since ordered all stations, including areas of Bhiwandi, Kalyan and other parts of the city, to maintain heightened vigil. “We urge citizens to verify their credentials before renting properties or hiring domestic workers,” Dumbre said, warning that many undocumented immigrants rely on local assistance to obtain falsified government identification documents.The authorities issued 284 restriction orders as part of the administrative machinery supporting the campaign. Of these, 271 deportation orders were successfully executed. At the end of December there were only 13 cases pending, a number that officials hope to resolve soon. Authorities say law enforcement will continue unabated. “Those found violating immigration laws will face strict legal action and immediate deportation,” a senior official said, adding that the pace of new registrations is expected to remain high as ongoing investigations mature. “The campaign is part of a broader national effort to identify and expel undocumented foreigners, with Maharashtra emerging as a key front in that effort,” the official said.
