The Boston Police Department reports that after a Dorchester 16-year-old gets out of the hospital, he'll be formally charged with a variety of gun offenses for a fight at the Morton Street Walgreens in which he managed to shoot both his opponent and himself Friday night.

Police say the teen - already facing an outstanding warrant on a charge of being delinquent for armed robbery - showed up at the Walgreens shortly before 9:40 p.m. to buy a phone from a 20-year-old man. He handed over the money and got the phone, but before he left, the seller realized some of the money was counterfeit and demanded satisfaction from the kid, according to police. An argument turned into a fight and the teen pulled out a .380 caliber AMT handgun, police say:

"As the two continued to struggle for control of the weapon, two shots were fired outside, one of which struck the suspect. The fight continued and spilled into the store, where the armed security guard standing inside the doorway ordered the suspect to drop the gun and the fight concluded. Officers asked the victim if he had been injured in anyway during the incident at which time he then realized that he too had been shot. Both the victim and the suspect were transported to area hospitals for treatment of their injuries which are considered non-life threatening."

Police say that on his release from a local hospital, where he remains in guarded condition, he will be booked on charges of being delinquent for assault and battery with a dangerous weapon, assault with intent to rob, unlawful possession of a firearm, unlawful possession of ammunition, discharging a firearm within 500 feet of a dwelling and carrying a loaded firearm on a public way.
