The blast occurred beneath the flyover in front of the Moghbazar Freedom Fighters’ Memorial, a busy location frequented by pedestrians and commuters.

Witnesses said the device was thrown from above the flyover and detonated on the ground below, critically injuring the victim.

Relatives later identified the deceased as Siam, who worked at a private factory and happened to be in the area at the time.

His identity was initially unknown, but it was confirmed after family members arrived at the scene. He succumbed to his injuries shortly after the explosion.

Police cordoned off the area soon after the incident as panic spread locally. The attackers fled immediately after throwing the explosive.

Masud Alam, Deputy Commissioner of the Ramna Division of the Dhaka Metropolitan Police, told the media that preliminary findings indicate the bomb was thrown downward from the flyover.

“The motive has not yet been confirmed,” he said, adding that an investigation is underway.

No group has claimed responsibility so far.
