A Dhaka court today placed three suspected members of banned Islamist outfit Jama'atul Mujahideen Bangladesh (JMB) on a four-day fresh remand in a case filed under Anti-Terrorism Act.

Metropolitan Magistrate Md Yunus Khan passed the order after the detectives produced them before the court seeking their remand for seven days for each of them.

The Detective Branch of police produced the militant suspects before the court on completion a six-day remand in the same case.

The detectives in their forwarding report to the court said the suspects are needed to be interrogated further to extract information about two absconding militants.

Earlier on December 25, the three were placed on a six-day remand in connection with a crackdown at an alleged militant den in Dhaka's Mirpur the previous day.

The DB filed the case under the Anti-Terrorism Act against the three and two other absconding militant suspects over the raid at the alleged den.

In a 15-hour crackdown in a 'JMB' den at Mirpur, detectives on December 24 seized 16 improvised grenades, other ingredients, including enough power gel to make over 200 bombs and grenades, and a suicide vest, according to police.

Six youths, aged between 20 and 30, were said to be detained during the raid at two apartments on the top floor of a six-storey building in Shah Ali area.
