DHAKA, Oct. 26 (Xinhua) -- Bangladesh's elite force -- Rapid Action Battalion -- Sunday night arrested six militant including two top leaders of a banned Islamist outfit with huge explosives, a senior official said Monday.

    Senior spokesman of the South Asian country's elite force Sakhawat Hossain told Xinhua Monday, "Six members of the banned Islamist outfit Jamaatul Mujahideen Bangladesh (JMB) was arrested after a nightlong crackdown in three districts of the country."

    Rapid Action Battalion (RAB), specially assigned to focus on curbing organized crime and eliminating top criminals, also retrieved 19 grenade bodies, 20 detonators, one pistol and huge bomb making materials from possession of the militant, he said.

    Out of the six arrested militant, Hossain said, "Two JMB men during primary interrogation were identified as members of Majlis-e-Shura, top decision making body for the banned Islamist outfit JMB."

    JMB, campaigning for establishment of Islamic rule in Bangladesh, staged synchronized serial bombings in 63 out of the South Asian country's all 64 districts including capital Dhaka on Aug. 17, 2005, leaving two people dead, 150 injured.

    JMB Chief Sheikh Abdur Rahman, his second-in-command Siddiqul Islam alias Bangla Bhai and four other top leaders were hanged in 2007 for killing two judges in Bangladesh's southern Jhalkathi district, some 182 km away of capital Dhaka, in 2005.

    A RAB official on condition of anonymity said, "There is information that the JMB men are trying to be reorganized to create untoward situation in the country that's why we're continuing our drives to nab them."

    Earlier this month, RAB also arrested three people and retrieved 10 Arges grenades in Bangladesh's northern Sherpur district, some 188 km from capital city Dhaka.
