Fairfax County police officers, trying to break up a violent dispute between a man and his mother in the Newington area, shot both the man and one of their own officers yesterday, police said.

Neither was seriously wounded.

Three officers responded to a report of a domestic dispute at a townhouse in the 6700 block of Mockingbird Woods Court, just off Telegraph Road, about 6 a.m. Lt. Richard Perez, a Fairfax police spokesman, said the first officer saw a 23-year-old man assaulting his mother in the foyer of the townhouse.

"He's on the stoop, trying to defuse that and prevent further assaults," Perez said. "He engages the suspect."

The details of what occurred next were not released yesterday. Perez said the man was somehow drawn outside as the next two officers arrived.

"During the course of trying to prevent further assault between the man and his mother, the shooting occurs," Perez said. He said that the officers had been trying to talk to the man and that shots were fired on the sidewalk in front of the house.

The man was wounded in the upper body. One officer was shot in the foot. The man was flown by helicopter to Inova Fairfax Hospital, where police said his condition was not life-threatening. The officer also was hospitalized for his foot wound.

Asked if the man was armed, Perez said: "We're still trying to determine that. There's a possibility he might not be armed."

Fairfax police, as is their practice, would not release the names, ages or years of experience of the three officers involved in the shooting. All three were assigned to the Franconia station, and all have been placed on leave with pay pending an investigation, Perez said.

The man's name also was not released, and police did not know if he lived at the townhouse. Although Perez said the man's mother was injured in the fight with him, no charges were filed yesterday, as police continued to sort out the incident.
