Rab has collected fingerprints and DNA samples to identify the three militant suspects killed in Tuesday's anti-terror operation in Chapainawabganj.
“We are trying to identify them,” Lt Col Mahbub Alam, commanding officer of Rab-5, told The Daily Star.
The suspected members of banned militant outfit Jama'atul Mujahideen Bangladesh were killed after they had allegedly detonated suicide vests during Rapid Action Battalion's raid on a house at Moddho Char village in Chapainawabganj sadar.
“It seems they exploded their suicide vests,” said Mufti Mahmud Khan, Rab's legal and media wing director.
The suspects were buried after autopsies at Chapainawabganj Sadar Hospital morgue yesterday.
Nadim Sarkar, residential medical officer at the hospital, said they died in the explosions.
Rab officers said they were searching the remote area for more suspects, explosives, arms and ammunitions.
Three improvised explosive devices, seven detonators, 12 packs of explosive gel and two pistols were recovered from the scene of Tuesday's raid.
Owner of the house, his wife and mother-in-law are still being detained by Rab. Officers said they would decide whether to arrest them in a case filed over the incident after further interrogation.
Saber Reza Ahmed, officer-in-Charge of Chapainawabganj Sadar Police Station, said no case was filed in connection with the incident.
