A 16-year-old Mount Rainier youth was shot and seriously wounded last night as he struggled with a D.C. police officer for control of the officer's gun in an alley between Harvard and Irving street NW, police officials said.

The youth was taken to Washington Hospital Center where he was being treated early today for a gunshot wound to the abdomen, police said. He was charged with unauthorized use of a vehicle and assault on a police officer.

Officer William Welch was treated for bruises on his face, arms and chest suffered in the incident, police said.

Officials said the incident occurred after Welch observed the youth get into a parked stolen 1969 Pontiac the officer had been keeping under surveillance in the 1200 block of Harvard St. NW, and then drive away.

Welch followed the stolen car for about one block on Harvard Street where he tried to make an arrest, but the youth put the Pontiac into reverse, struck the police car and then sped away, officials said.

Welch chased the car to the 700 block of Harvard, where the youth jumped out and ran into an alley, officials said. Welch caught up with the youth and during an ensuing struggle for the officer's service revolver, the gun fired, officials said.
