Former Bull Scottie Pippen turned himself over to police to be questioned about his involvement in a fight outside of a tony Malibu sushi restaurant over the weekend that sent a man to the hospital, officials said.

Pippen had been at the Nobu Malibu restaurant on the Pacific Coast Highway when a fight broke out between him and the man around 6:30 p.m. Sunday, said Steve Whitmore, a spokesman for the Los Angeles County sheriff's office.

"He came in to be interviewed, he's been cooperative," said Whitmore.

By Monday afternoon, Pippen had been questioned by police and was cooperative, said Whitmore. Pippen was allowed to leave without being charged, said Whitmore.

"Mr. Pippen will not be arrested, there's more here than meets the eye," said Whitmore.

He said the investigation was continuing. "We have to investigate and check with all the witnesses and find out exactly what happened," said Whitmore.

Earlier, Pippen was named as a suspect and was facing possible charges of assault with intent to cause great bodily injury, Whitmore said.

Witnesses told police Pippen got into an argument with a man in the parking lot of the restaurant near a valet stand, Whitmore said.

"That argument led to an altercation," Whitmore said. "Our detectives are investigating this right now."
