From TMZ:

Chris’ lawyer, Mark Geragos, has already contacted detectives and said the singer is ready, willing and able to give them the blow-by-blow, because he knows he did nothing wrong.

What’s more … sources say Geragos’ team has surveillance video of the last part of the fight, and Chris is as clean as a whistle — not throwing a single punch.

But here’s the thing. We’re told the video also clears Frank Ocean — he never takes a swing at anyone. The fighting is between the two posses.

The video, however, is not the be-all and end-all, because it only captured the back end of the fight. The altercation began in the parking lot and no cameras were trained on the action. So it doesn’t show who started it. The fight moved into the lobby, and that’s where the camera captured the brawl.

Chris’ account is radically different from a witness who claims Chris threw the first punch.

As for why Chris booked it before cops arrived, we’re told Geragos gave him the strictest of instructions … if he ever got in a situation where trouble was brewing, he MUST leave immediately.

Look like Chris Brown might get hit for violating parole, because according to the New York Post, Frank Ocean wants to press charges against his attacker:

R&B singer Frank Ocean intends to press charges against bully boy Chris Brown for punching him and starting an all-out brawl outside Westlake Studios in West Hollywood on Sunday night.

Police want to talk to Brown, who is still on probation for beating up Rihanna on the eve of the 2009 Grammy Awards.

Ocean, who publically came out in July as a bisexual, is “desirous of prosecution,” L.A. Sheriff’s Office spokesman Steve Whitmore told The Post. “We’ll find out what happened.”

The fight over a parking space reportedly involved six men. Ocean tweeted: “got jumped by chris and a couple guys. Lol. I only wish everest was there.” Everest is his dog.

He later added: “cut my finger now I can’t play w two hands at the grammys.”
