Four private madrasas in Assam have been demolished in three districts in the past one month over the alleged links with the terror outfits and attempts to set up "jihadi sleeper cells" in the northeastern state. Since April this year, Assam Police have arrested around 40 terror suspects in connection to AQIS-backed modules and a strict vigil is being maintained, particularly in the minority-dominated areas of western and central Assam. Many of the detainees are imams at mosques or teachers at private madrasas.
