Gunfire followed by arrest in Dorchester

Boston Police report officers responding to a call about gunfire at Columbia Road and Seaver Street around 3:40 a.m. spotted a guy walking quickly away while clutching at his waistband:

Officers stopped their vehicle and were preparing to exit in order to speak with suspect when he suddenly took off running. Officers pursued the suspect on foot and were closing in on him when they observed him pull a firearm from his waistband and discard it on the sidewalk. The firearm was later recovered and determined to be a loaded .32 caliber Regent revolver with an obliterated serial number.

After a "brief but violent struggle," officers arrested Joquentz Constant, 22, of Dorchester, on charges of unlawful possession of a firearm, unlawful possession of ammunition, carrying a loaded firearm, possession of a firearm with an oliterated serial number and resisting arrest, police say.

Innocent, etc.
