At about 7:17 PM on Thursday August 8, 2019, officers assigned to District D-4 (South End) arrested a juvenile suspect after responding to a call for a person with a gun in the rear parking lot of the Blackstone Innovation School located at 380 Shawmut Avenue in the South End. On arrival, officers observed an individual matching the given description and approached to speak with him. Upon seeing the officers, the suspect, later identified as a 14-year-old from Roxbury, immediately took off running but was stopped a short distance away by additional responding officers. Officers placed the suspect in custody after recovering a firearm, which was later revealed to be a Daisy Powerline 340 BB gun, and an MTech Extreme knife with a brass knuckle handle from inside a back pack the suspect was carrying. The suspect will appear in Boston Juvenile Court on charges of Delinquent to Wit: Possession of a BB Gun and Dangerous Weapons Unlawfully Carried.
