Mattapan Officers Arrest 17-year-old with a Large Capacity Firearm

On Wednesday, May 7, 2025, officers assigned to District B-3 (Mattapan) arrested a 17-Year-Old Juvenile Male, on multiple firearm offenses.

At about 8:07 PM, officers were patrolling the area of Woodmere Avene when they observed a group of four males walking in the area. One of the individuals was walking with his right arm pinned to his body, and began to manipulate an unknown object in his waistband area.

At this time, officers exited their cruiser to investigate further. Officers approached the group and immediately approached one of the individuals as they feared he was armed with a weapon. A pat frisk was conducted, and officers observed the handle of a firearm sticking out of the front of his waistband.
