Two people were arrested for separate stabbing incidents in Roxbury and Dorchester on Saturday, BPD reported Sunday, and one 14-year-old boy was arrested with a gun in Hyde Park on Friday.

On Friday, members of the Youth Violence Strike Force were conducting a missing person investigation in the area of 6 Alwin Street for a juvenile with an outstanding warrant, the police said.

Around 2 p.m., officers reportedly saw the kid enter an idling car with a second person and intiated a traffic stop as the vehicle moved.

BPD said officers made contact with all people in the car, had them exit the vehicle. They searched the car, BPD said, and found a firearm, later determined to be a Kel-Tec Sub-2000 Rifle with 15 rounds in the magazine.

The other car occupants were “promptly released,” police stated.

The 14-year-old suspect was placed under arrest and charged with Delinquent to wit; Unlawful Possession of a Firearm, Delinquent to wit; Unlawful Possession of Ammunition, and Delinquent to wit; Unlawful Possession of a Large Capacity Feeding Device.

The suspect is expected to be arraigned in Boston Juvenile Court, BPD said.

Police also made arrests in two stabbing incidents on Saturday.

The first suspect, Michael Josey, 62, was arrested on Assault and Battery charges at about 6:13 p.m. in Roxbury, police said.

Police responded to a report of a male stabbing a victim in the area of 493 Blue Hill Avenue and fleeing the scene, BPD said.

The responders reportedly saw a man matching the suspect’s description leaving the scene with a screw driver and stopped the man.
