By all accounts, it was a really wild police chase. Three youths in a car reported stolen in Maryland's Prince George's County were pursued at speeds topping 100 miles an hour along Rtes. I-66 and I-495 in Virginia before dawn yesterday before finally being stopped near Annandale.

A 16-year-old Washington youth was arrested immediately, but his two companions dashed across the Capital Beltway, police said, only to be picked up about 9 a.m. after a search of a wooded area involving a Virginia State Police helicopter and a Fairfax County K-9 unit.

Cpl. Ron Sullins of the Prince William County Police Department said the chase of about 25 miles began near Manassas when Officer Steve Reed sought to stop the car for a routine check. The car, its headlights turned off, headed east on I-66 toward Washington.

According to Warren Carmichael, Fairfax County police spokesman, Reed was joined by four Fairfax units and, at the I-66 interchange with I-495 (the Beltway), by several state police cruisers. They formed a "box" that forced the young driver to lose control and stop between the Gallows Road and Little River Turnpike interchanges on I-495.

All three youths were returned to Manassas. Cpl. Sullins said he could not list the specific charges that would be filed against them.
