The arrest took place in Hampden County in Springfield around 7 p.m., Thursday, May 5 on Walnut Street.
The teen was arrested after Springfield detectives received information that he was currently in possession of a firearm in a parking lot on the 400 block of Walnut Street, said Ryan Walsh, spokesman for the Springfield Police Department.
Detectives approached a group of four teens, including the suspect, who was detained, Walsh said.
During a search, detectives recovered a firearm from inside a chest pack the teen was wearing and placed the juvenile under arrest, Walsh added.
Due to his age, the teen's name is not being released.
