Law enforcement members have told the Dhaka Tribune the twin bombs that exploded in Shibbari, Sylhet outside a militant den during an ongoing raid were ‘time bomb-like’ devices.
Sources in the Sylhet Metropolitan Police (SMP) bomb disposal unit said on Sunday that the bombs, which killed two of their colleagues, had timers attached to them.
One of the bombs went off in the middle of a crowd around 6:45pm Saturday, injuring over 40 people and killing one man, initially believed to be the attacker. Two of the injured, both local residents, died at Sylhet MAG Osmani Medical College Hospital within the night.
The other exploded minutes later while the SMP bomb disposal unit was trying to diffuse it, injuring Rapid Action Battalion’s intelligence chief Lt Col Abul Kalam Azad and several other officials.
SMP Special Branch’s Inspector Moniruzzaman, SMP court Inspector Chowdhury Abu Kawsar, South Surma Chhatra League leader Jannatul Fahim, City Chhatra League leader Ohidul Islam Opu, the suspected bombers Shahidul Islam and Khadim Shah were killed in the twin blasts.
The two inspectors succumbed to their injuries at the Osmani hospital. Lt Col Azad has been flown to Singapore for treatment in critical condition from Dhaka’s Combined Military Hospital.
SMP Additional Commissioner SM Rokanuddin said: “The bombs in Shibbari were different from what we have seen so far. We are investigating this matter.”
He refused to say more.
Assistant Sub-Inspector Jony Lal De, who was also injured in the second blast, told the Dhaka Tribune at Osmani Hospital that the bomb they were trying to diffuse was rectangular in shape.
The policeman, who was in post-operative care, said when they found the bomb from the spot, it was inside a black polythene bag with some vegetables on top.
Another of his colleagues, SI Masud Parvez, was also injured in the attack and was being treated at the hospital.
