At about 1:43 AM on Saturday September 24, 2016, officers assigned to District B-3 (Mattapan) made an onsite firearm arrest after shots were fired in the area of Eerie and Ellington Streets in Dorchester. The officers were on patrol when they heard the sound of gunfire within close range and then observed a male walking quickly from the area while clutching at his waistband, leading officers to believe he was in possession of a weapon. Upon seeing the officers, the suspect, later identified as Anthony Tabb, 23, of Brockton, immediately took off running. The officers chased the suspect for several blocks and called for additional units after the suspect entered a private backyard at 11 Fowler Street and could not be located. The suspect was found hiding underneath a ladder by BPD K-9 Duke (pictured above left) and placed in custody. BPD K-9 Boomer (pictured above right) then retraced the suspect's path of flight and located a loaded .40 caliber Smith & Wesson SD40 VE handgun. The firearm has been turned over to the BPD Ballistics Unit for processing. The suspect will appear in Dorchester District Court on charges of Trespassing and Resisting Arrest, although, additional weapons charges could be added at a later time pending the outcome of the investigation.
