The Rapid Action Battalion (Rab) filed two cases over the death of two suspected Jama'atul Mujahideen Bangladesh (JMB) members in a raid by the elite force in Gazipur.

Both the cases were filed under the arms and explosive substances act with Joydebpur Police Station on Monday, said Khandaker Rezaul Hasan, officer-in-charge, of the police station.

According to the case statements, a Rab team raided an abandoned tin-shed building adjacent to a mosque at Jogitola in Gazipur on Sunday evening. The team had information that some militants were planning subversive activities there.

Sensing presence of the Rab, the criminals started to hurl bombs at them, prompting the team members to retaliate with gunfire.

At one point, a bomb blast took place inside the building. The Rab team entered it around 2:30am Monday and saw two severely injured men on the floor.

The duo was rushed to local Shahid Tajuddin Ahmed Medical College Hospital where on-duty doctor declared them dead.

A loaded foreign pistol, remains of four bombs that went off, 29 detonators, two kgs of explosive materials and four Jihadi books were recovered from the spot, added the case statements.

Meanwhile, the identities of the duo could not be known till yesterday. No one claimed the bodies kept at the morgue of Gazipur hospital.

OC Rezaul of Joydebpur police said they will hand over the bodies to charity organisation Anjuman Mofidul Islam today, provided those remain unclaimed.
