Rapid Action Battalion arrested two leaders and a member of the banned Jama'atul Mujahideen Bangladesh (JMB) outfit from different parts of the capital on Monday.
The elite force members also seized several JMB publications and leaflets from the possession of the arrestees, Major Walid Md Saifullah, deputy director of Rab's Media and Legal Wing, told The Daily Star.
The trio was identified as Mohammad Asaduzzaman alias Hazari, chief of JMB Khulna divisional unit, Md Wahab, head of JMB Savar zone and JMB member Anwar Hossain.
Asaduzzaman, a Majlish-e-Sura committee member of JMB, was arrested from Sayedabad, Wahab, a gayeri ehsar (part-time) member was picked up from Gabtoli while Anwar was arrested from Abdullahpur in Uttara, the Rab official said.
The arrestees were produced before a press conference yesterday at Rab Headquarters of Uttara where Commander Mohammad Sohail, director of Rab's Media and Legal Wing said Wahab and Asaduzzaman were arrested on information squeezed out of Anwar.
He said all three were fugitives in the series bomb attack cases of 2005.
There are a total five cases against Asaduzzaman with several police stations in Shatkhira. He is said to have led the August 17, 2005 bomb attacks at Shatkhira and was reportedly assigned by Shaikh Abdur Rahman.
Wahab is an accused in two cases filed with police stations in Savar and Anwar is an accused in two cases.
Rab officials are interrogating the arrestees for more information.
Commander Sohail said they are trying to find out if any banned outfits like JMB are plotting any subversive activities ahead of BNP's March 12 political programme as militants try to take advantage of mass political events for such activities.
