Waltham Police arrested a 16-year-old Waltham man on Dec. 14 after he allegedly robbed a gas station with a BB gun.

The incident started at around 9:57 p.m. on Dec. 14 when police responded to a report of an armed robbery at Colvin's Gas Station at 185 Prospect St., according to police. The robber had allegedly passed a note to the station clerk demanding an undetermined amount of money and fled the store with some cash, according to police. 

Officers arrived and searched the areas of Curtis and Highland Streets and found a man matching the robber's description, according to police. The man fled but officers chased him as they waited for backup. Police eventually captured the suspect near 20 Hope Ave.

Police later found a black BB gun and money they believe was taken from the store.

The suspect, whom police declined to name because he is legally considered a juvenile, is charged with armed robbery and resisting arrest. He was later released into his parents' custody and will be arraigned at Waltham District Court in the near future.
