<h1>Illegal immigration enforcement leads to mass detention and interrogation, with deportation proceedings for those lacking valid documents.</h1> A coordinated multi-agency enforcement operation in Ahmedabad detained over 450 persons alleged to be illegal immigrants, mostly from Bangladesh. Detainees were held at a designated ground for interrogation to verify documentary status; those found without valid documents face administrative removal, including deportation. The operation involved crime branch, special operations group, economic offences wing, and zone police personnel conducting combing actions across the city.
