Police have filed two separate cases under the Special Powers Act against protesters demanding justice for the murder of Imam Rais Uddin in Chattogram. Twenty-two activists were sent to jail on Tuesday following court proceedings. Meanwhile, Islami Chhatra Sena held a black flag procession condemning the brutal attacks on protesters and demanding the arrest of the killers. The group alleged that helmeted assailants armed with local weapons attacked demonstrators in front of the police, and some of them were linked to Jamaat-Shibir—but no arrests have been made.
