The fire that started at the ground floor of a six-storey building named Haji Musa Mansion, left four people, including a woman, dead and injured 24 others, including three firemen.

"They have been charged with deaths due to negligence and keeping illegal chemical substances in the building.
"We are carrying out investigation and conducting drives to arrest the accused," the police official added.
Old Dhaka remains a ticking time bomb during fires because of illegal chemical warehouses, unplanned building construction, narrow roads and high population density.
In February 2019, a devastating fire at Wahed Mansion in the Churihatta area of Chawkbazar claimed 71 lives.
In June 2010, a deadly fire in Nimtoli took 124 lives.
