Chapainawabganj: Law enforcers were getting ready to launch a raid on a 'militant den', which was cordoned off on Wednesday morning at Shibnagar Trimohoni in Shibganj upazila of Chapainawabganj.

A Special Weapons and Tactics (SWAT) team of the Counter Terrorism and Transnational Crime (CTTC) under Dhaka Metropolitan Police joined police in the afternoon to conduct the drive, said police.

The SWAT team reached the spot by a helicopter at about 4:45pm.

However, police could not exactly say when the drive will begin.

Tipped off, police encircled the suspected militant hideout at about 5:30am, said officer-in-charge (OC) of Shibganj Police Station Habibul Islam.

"The militants fired several gunshots from the house towards the law enforcers in the morning," the OC told UNB.

Later, a CTTC team joined the police, he said.

Meanwhile, the district administration imposed section 144 in and around Shibangar Trimohoni for the sake of security of locals and to ward off any untoward incident, said a CTTC official, adding they have already taken the residents of the adjacent houses to safer places.

The CTTC suspects that there are 3-4 militants, including one Abu, in the house.

Locals claimed Abu along with his family rented the house two and half months ago introducing him as a spice vendor.
