A man, allegedly involved in a shooting incident on August 12 which left a detective injured, was killed during a “gunfight” in capital's Jurain early yesterday.

The deceased was identified as Mamun, 30.

Police claimed he was a local criminal involved in arms trading.

During primary investigation it was learnt that Mamun shot Rahul Patwari, senior assistant commissioner of detective branch (west division) of Dhaka Metropolitan Police during a raid to recover arms on that day.

Abdul Baten, joint commissioner of detective branch of Dhaka Metropolitan Police, said Patwari was wounded in his abdomen.

The DB official said a team of detectives on Monday arrested one Shantonu from Jatrabari on charge of involvement with the shooting incident that left the police AC, a police informant and another man injured.

Shantonu admitted his involvement in the shooting and informed detectives about his associates including Mamun.

A detective team went to Jurain graveyard area around 2:00 am yesterday to nab the gang when they opened fire on the team forcing the law enforcers to retaliate. Mamun died in the ensuing gunfight.

Police recovered two pistols from the spot. “We will send those for ballistic test to confirm whether any of the firearms was used in the August 12 incident,” Baten said. 

Mamun's body has been kept at Dhaka Medical College mortuary after autopsy. Morgue sources said Mamun sustained one bullet in the head. 

AC Rahul Patwari, meanwhile, was released from Dhaka Medical College Hospital on Monday.

The police informant Belal Hossain Mridul was shot in the left leg while Selim, a driver at a nearby tea stall, was hit on his back.
