A Pierce County sheriff's spokesman says a Puyallup (Pew-ALL-up), Wash., school bus with elementary school children aboard was clipped Tuesday afternoon by a car fleeing the scene of a nearby shooting.

Detective Ed Troyer says no one was injured in the crash. About 20 children were taken off that bus and taken away in another bus.

Troyer says a silver car was involved in a shooting a half dozen blocks away. That car fled and eventually struck the bumper of the school bus.

Investigators originally believed the bus had been struck by gunfire, but later corrected that report.

Detectives are trying to track down the car. No details were immediately available on the nearby shooting.

Puyallup is southeast of Tacoma.
