A 63-year-old man was fatally injured and his wife seriously injured when a stolen car being chased by D.C police into Virginia slammed into the rear of their car last night on Seminary Road in Alexandria, authorities said.

The couple's identity and place of residence were not immediately released, and the condition of the woman, who was flown by helicopter to Fairfax Hospital, could not be learned.

Officials at Alexandria Hospital said the man was pronounced dead early today.

D.C. police said the chase began about 11:20 p.m. on or near the Southwest Freeway and that after the crash a man believed to be the driver of the car that was being pursued was arrested while attempting to flee on foot.

First District Sgt. R. Hanbury said Officer Rodney Parks, who had noticed a car being driven erratically while on his way to work and later determined from the police computer that the car was stolen, spotted the vehicle, occupied by three persons, and began the chase.

The pursuit, at high speed, proceeded across the 14th Street bridge onto Shirley Highway in Virginia, with two other police cars joining in, Hanbury said.

The car then turned onto Seminary Road and the chase ended in the 5200 block of that street when the car smashed into the sedan occupied by the couple, Hanbury said.

Hanbury said all three occupants of the car that had been pursued ran into an alley and one, believed to be the driver, was arrested and charged with involuntary manslaughter in Alexandria and with grand larceny of an auto in the District of Columbia. The suspect's name was not immediately available.
