Police say nine people were injured in a shooting outside a concert sponsored by a San Francisco radio station.

Police say the gunfire erupted outside the Regency Center around 10:30 p.m. Sunday after two groups of people got into a fist fight following a concert sponsored by radio station KMEL.

The nine injured were taken to hospitals with non-life threatening injuries.

Police detained one person, who they say had weapons on the trunk of his car. They have not identified the person, and witnesses have reported he was not the shooter.

Police are continuing to look for suspects and have made no arrests.
