The deceased was identified as Khokon, 30.
Tipped off that a robber gang was preparing for committing robbery in Bakara Canal area, police conducted a drive there around 2am, said Rashedul Alam, officer-in-charge of Moheshpur Police Station.
Robbers fired at police as soon as they reached the area, forcing them to fire back in self-defense which triggered a skirmish, the OC added.
He said police later recovered the body from the spot.
Khokon was wanted in several cases, he added.
