At about 10:45 PM on Sunday August 14, 2016, officers assigned to District B-3 (Mattapan) made an onsite firearm arrest in the area of 134 Whitfield Street in Dorchester. Officers were called to the area in response to a large house party which had spilled out onto the street where several fights had broken out and the suspect had displayed a firearm. As the officers arrived on scene, they observed the suspect, Rakeem Lewis, 23, of Dorchester, standing in the street about fifteen feet in front of their cruiser. Upon seeing the officers, the suspect quickly turned and began running in a full sprint while pushing several people out of the way as he fled. The officers gave chase and pursued the suspect for several blocks before finally placing him in custody in the area of 51 West Tremlett Street. The officers then recovered a loaded 9mm Smith & Wesson handgun from the suspect’s short’s pocket and discovered that he was wearing a bulletproof vest. Just prior to apprehending the suspect, the officers heard the sound of gunfire close by but could not determine the source. The suspect stated to the officers, “I didn’t pop off, I didn’t pop off” as he tried to assure the officers that he had not discharged his firearm. The officers learned that the suspect was licensed to carry a firearm but was in violation of his restrictions at the time of the incident. As a result, his license to carry and the firearm were seized. The suspect will appear in Dorchester District Court on charges of Carrying a Firearm in Violation of Restrictions and Disturbing the Peace.
