Mirza Azam, who was undergoing treatment at the institute with 80 percent burns, died around 9:30am, Samanta Lal Sen, chief coordinator of the hospital, told The Daily Star

The body was brought out from the severely damaged building around 12:15pm

"Around 4:30 or 4:45pm, the ceiling and the walls began to collapse following a big blast. I cannot remember much of what happened afterwards."

According to their primary observations, the seven-storey building is in a risky state now, and the slab of the ground floor has also collapsed

In light of previous experiences, Kamal Uddin said he has the ground to suspect it could be a case of sabotage.

The commissioner said they will look into whether there was any septic tank or leakage in the basement as the explosion occurred there.

At the spot, an on-duty Rab official was heard speaking on his mobile and requesting a top official of Rajdhani Unnayan Kartripakkha (Rajuk) to send an engineer for clearance

In a condolence message, the PM prayed for eternal peace of the departed soul and asked authorities concerned to take prompt and necessary measures to ensure better treatment of the injured
