LA Sheriff: Chris Brown investigated for possible assault in fight over parking spot

WEST HOLLYWOOD, Calif. - Authorities are investigating allegations that Grammy-winning singer Chris Brown assaulted a man in a West Hollywood parking lot.

The Los Angeles County Sheriff's Department says deputies responded to a report Sunday night of six men fighting.

Witnesses told deputies that the brief fight was over a parking space.

The department says the "altercation allegedly led to Chris Brown punching the victim."

The "victim" wasn't identified but the celebrity website TMZ, which first reported the incident outside a recording studio, says the fight also involved Frank Ocean, a nominee in the upcoming Grammy Awards. He later tweeted that he "got jumped by (Brown) and a couple guys" and suffered a finger cut.

The department says it will contact Brown later.

Brown's attack on singer Rihanna on the eve of the 2009 Grammy awards overshadowed the show. He was injured in a June 2012 brawl with members of hip-hop star Drake's entourage at a New York nightclub.
