The Bagerhat police have arrested three more JMB activists, including two siblings, from a village under Mollahat upazila and Daulatpur in Khulna district on early Monday. The police said that the siblings, Kalim Mollah, 30, and Jasim Mollah, 22, are activists of the JMB, and their father, Hekmot Mollah of Udaypur village, is a close associate of Siddiqul Islam alias Bangla Bhai, the chief of banned Islamist outfit Jagrata Muslim Janata. The two were nabbed from Khulna while the other, Zillur Rahman, was arrested from his village in Mollahat. The three reportedly divulged important information in connection with the bomb blasts in Bagerhat town. It was alleged that Bangla Bhai took shelter in their house in 2003 when he allegedly went to Mollarhat in a bid to kill one Tarapada Poddar of Gaola.
