Four alleged militants surrendered from a house cordoned off by members of Rapid Action Battalion (Rab) suspected of being a hideout in Shahjadpur upazila of Sirajganj district on Friday morning.
They came out of their den at Ukilpara after 10:30am and gave in to the elite force.
One of them was said to the chief of the Pabna-Sirajganj region of Jamaat-ul-Mujahideen Bangladesh.
A special Rab team from Dhaka joined the drive at the suspected militant den.
Details of the raid will be disclosed through a press conference, said Rab sources.
Earlier, the crime-busting force cordoned off the house in the early hours suspecting it to be a militant hideout.
