The deceased were Altaf Hossain, 40, Antar, 25 and Mofizul Islam, 20, said Anwar Hossain, a sub-inspector (SI) of Sabujbagh Police Station.

They fell when the rope of the scaffold snapped around 9:45am, said Rabindra Nath Sarker, another SI of the police station.

With critical injuries, they were rushed to the Mugda Medical College Hospital where doctors declared Altaf and Antar dead. Mofizul died around 2:00pm while undergoing treatment at the intensive care unit, Anwar said.
