OAKLAND, Calif. – The California Highway Patrol is trying to locate a group of drivers who briefly shut down part of a San Francisco Bay area freeway while they performed stunts in the middle of the road.

Sgt. Rob Barrera said Monday that the CHP is confident that someone will be prosecuted for the brazen sideshow that stopped traffic on Interstate 880 near the Oakland Coliseum on Saturday afternoon. Barrera declined to comment further. Video clips show at least a half-dozen cars peeling out from the shoulder and doing doughnuts in the road while other vehicles stack up behind the demonstration.
