A juvenille and an adult suspected of trying to kill two police plainclothes officers in Arlington led police on a high-speed car chase into the District of Columbia last night. A half dozen patrol cars and two helicopters were involved before the car being pursued struck a pole and two suspects were apprehended in Northeast Washington.

Arlington police said the chase began shortly after 8 p.m. when two plainclothes detectives approached a yellow Cadillac in the 4200 block of South 35th Street in Fairlington, suspecting it to be a getaway vehicle in a burglary that had just been reported. Police said the car almost ran the detectives down and the officers responded by firing several shots.

Arlington police gave chase and were joined by D.C. police cars and U.S. Park police helicopters as the car sped from Rte. I-395 across the 14th Street Bridge into the city at speeds up to 75 miles an hour. The chase proceeded through the waterfront and Capitol Hill areas before the car struck a utility pole at Ninth and East Capitol streets, police said. Suspects were arrested on foot in the 1200 block of C Street NE.

Charged in a fugitive warrant with attempted murder were Marcus Johnson, 19, of 932 T St. NW, and a 17-year-old.
