Police in the port city, Chittagong, on Saturday quizzed the chief of a controversial madrasah linked to Hefajat-e-Islam, raiding the seminary as a nationwide anti-militancy crackdown is underway.
Quoting officials and witnesses BSS said several hundred policemen in riot gears kept the Al Jamiatul Ulum Al Islamia Madrasah at Lalkhan Bazar under siege while the personnel of the law enforcement agency inspected its dormitories and other parts.
Hefajat-e-Islam leader Mufti Izharul Islam Chowdhury runs the madrasah with his son Harun Izhar being its director.
The official said they find no direct evidence this time suggesting the madrasah's militancy link this time though police had recovered four grenades and bomb-making materials two years ago from the scene after what it appeared an accidental blast at that time.
The blast on the second-floor of the madrasah's four-storey dormitory wounded seven of students on October 7, 2013 prompting a subsequent police raid there.
Both the senior and junior Izahars were arrested following the blast but they later obtained bail from the High Court.
