Chris Brown investigated for possible assault

Grammy-winning singer Chris Brown is under investigation for an alleged assault in a West Hollywood parking lot, the Los Angeles County Sheriff’s Department said early Monday, and fellow singer Frank Ocean tweeted that he had been attacked.

Deputies responding to a report of six men fighting Sunday night found the scene clear, but witnesses told them there had been a brief fight over a parking space.

“The altercation allegedly led to Chris Brown punching the victim,” the department said in a statement.

The victim wasn’t identified, but the celebrity website TMZ.com - which first reported the fight outside the Westlake Recording Studio - said it also involved Frank Ocean, one of the top nominees at Grammy Awards next month.

In a Twitter posting later, Ocean said he “got jumped by (Brown) and a couple guys” and suffered a finger cut.

Brown’s attack on singer Rihanna on the eve of the 2009 Grammy Awards overshadowed the show.

Last June, he was injured in a brawl with members of hip-hop star Drake’s entourage at a New York nightclub.

No arrests were made Sunday. The department said the investigation is ongoing.

Email messages to Ocean’s publicist and Brown’s lawyer were not immediately returned. A man answering the phone at the recording studio declined to comment.
