Four suspected militants, who were inside the house cordoned off by Rapid Action Battalion in Shahjadpur upazila of Sirajganj, surrendered this morning.
Lt Col Ashique Billah, Rab legal and media wing director, confirmed to media.
The suspected militants have been identified as Kiron alias Shamim alias Hamim of Sirajganj, Naimul Islam of Santhia in Pabna, Atiar Rahman alias Kolom Soinik of Dinajpur and Aminul Islam alias Shanto of Satkhira, reports our Pabna correspondent quoting Additional Director General of Rab Col Tofayel Mostafa Sarwar.
They were taken to Rab custody after surrender, he said.
"They rented the house saying that they are all students," said Rab ADG Tofayel, adding that as the house owner is a service holder and lives in Bogura, he did not scrutinise their identities.
They were regrouping the banned Islamist group in different districts of north Bengal and providing training to their operatives in Sirajganj, he said.
"Mahamud was arrested and sent to jail where he got to know a JMB leader and joined the banned group. On his release from jail, he started working to organise the banned outfit in north Bengal," Rab ADG Tofayel said.
It was primarily known that one of the four, named Kiron, is a suspected regional leader of banned militant group Jama'atul Mujahideen Bangladesh (JMB), said Lt Col Ashique Billah.
Members of the elite force cordoned off the suspected militant hideout in Ukilpara area since 5:00am based on information from two suspected militants arrested in Rajshahi last night.
Sensing the presence of law enforcement, criminals fired shots from inside the house.
Later, the law enforcers urged them to surrender through loudspeakers and mobile phones collected from the two arrestees.
No casualties were reported.
