California Highway Patrol officials are continuing to investigate a freeway "sideshow" stunt on an Oakland freeway over the weekend that took over the northbound lanes of Interstate 880 as drivers spun doughnuts.

CHP spokeswoman Diana McDermott said there have been no arrests.

"It’s extremely reckless, this type of driving," McDermott said at a press conference. "In no way are our freeway systems designed for this."

Videos popped up on YouTube and other social media after the Saturday afternoon stunt, showing several cars spinning in circles and burning rubber as several other drivers held back freeway traffic near the Oakland Coliseum Complex.

Officials believe six to eight cars were involved in the stunts, with several others helping to block traffic.
