A 15-year-old boy was arrested Thursday afternoon after police found him carrying a loaded pistol in Dorchester following a foot pursuit, officials said.
The boy was roaming down Colonial Avenue near Roberts Playground at 3:10 p.m. with three other boys who appeared to be in their teens, police said in a statement. Once the boy saw the officers in the area, police said he walked faster, separated himself from the others, and attempted to avoid eye contact.
Police also noticed the boy was pinning his right arm to his waistband, as if to hold something in place, and making frequent “weapons checks” to his right side.
When officers approached the boy, he immediately started running through backyards and onto Rosedale Street, where they found footprints in the snow leading to a parking lot on Aspinwall Road marked “No Trespassing.”
Officers found the boy hiding underneath a porch in the area and quickly arrested him. They later discovered a loaded 9mm Canik TP-9 semiautomatic pistol nearby and believe the boy threw it during his attempted escape, according to indications from thermal imaging scans.
The boy was arraigned in Dorchester District Court on charges of delinquent to wit, trespassing, unlawful possession of a firearm, unlawful possession of ammunition, and unlawfully carrying a loaded firearm.
He is being held on $25,000 bail at the request of prosecutors and will reappear in court on March 20, according to the Suffolk district attorney’s office.
