BOSTON— A large capacity firearm was seized by the Boston Police Department during a dramatic arrest on Tuesday, November 18, 2025. Officers from the Youth Violence Strike Force apprehended 18-year-old Antonio Walker, who was already wanted on an outstanding warrant for Assault and Battery with a Dangerous Weapon and Threat to Commit a Crime. The arrest unfolded at around 10 AM when officers stormed an apartment in South Boston.

Upon arriving, officers quickly handcuffed Walker and initiated a protective sweep of the premises. As they searched the apartment, they discovered a second suspect locked inside a bathroom. After persistent requests for the individual to exit, a 17-year-old juvenile male finally complied. Officers noticed a backpack adjacent to him, which raised immediate suspicions.

Boston Police Department officials shared these images with the public.

A pat frisk of the backpack led to the shocking discovery of a Glock 19 firearm loaded with eight rounds in an extended magazine, capable of holding a total of thirty-one rounds. The teen was arrested and is expected to face serious charges in Boston Juvenile Court, including:

• Unlawful Possession of a Firearm
• Unlawful Possession of Ammunition
• Carrying a Loaded Firearm without a License
• Unlawful Possession of a Large Capacity Feeding Device

This incident highlights a concerning trend of youth involvement in gun violence in Boston, with authorities emphasizing the need for swift action in addressing such alarming situations. The police continue to investigate the circumstances surrounding the firearm and its intended use.
