An activist of Islami-Chhatra Shibir was killed during a 'gunfight' with police in capital's Mirpur area on Saturday night.
The identity of the deceased could not be known immediately.
Rupnagar Thana SI Azizul Haque said, they arrested a Shibir man few days ago.
Acting on his statement, law enforcers alongwith the Shibir activist conducted a drive at Rupnagar area around 11:30pm.
Sensing the presence of law enforcers, miscreants opened fire on them, forcing police to fire back that triggered a gunfight.
"The Shibir man was caught in the line of fire and died on the spot" the SI said.
The body was sent to Dhaka Medical College Hospital morgue for autopsy.
