Stepping up security after a bomb blast at a police station, security agencies have launched a clampdown on militants arresting a kingpin of the Jamaatul Mujahideen Bangladesh (JMB) and six others.
The elite Anti-crime Rapid Action Battalion (RAB) officials said their troops arrested JMB's chief coordinator Motasim alias Basir alias Nasir along with his accomplices on Friday night.
They were arrested from Konabari area in Gazipur, police said, adding that they picked up four more suspected JMB operatives, including a woman on Saturday.
At least 15 people, including three journalists, were injured on Friday at the police station when a grenade seized in a raid was detonated by a suspected suicide bomber during a news conference in Gazipur on the arrest of four suspected terrorists.
Police and RAB officials said Saturday's arrest were the outcome of their long intelligence operations under their routine vigil against terrorist outfits.
