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. ||||| Chris Brown accepts the award for best R&B; album for ''F.A.M.E.'' at the 54th annual Grammy Awards in Los Angeles, California, February 12, 2012.

 LOS ANGELES (Reuters) - Rising R&B; artist Frank Ocean wants fellow singer Chris Brown prosecuted following a brawl over a parking space at a Los Angeles-area recording studio, authorities said on Monday. 
 
 Brown is serving five years probation for assaulting his on-and-off girlfriend Rihanna in 2009 and risks having his probation revoked should charges be filed. 
 
 In the incident on Sunday, sheriff's deputies responded to a call about a fight involving six men in West Hollywood. The deputies cited witnesses as saying that the Grammy-winning Brown, 23, punched Ocean during the brief altercation. 
 
 No charges have yet been filed, but Ocean "is desirous of prosecution in this incident," said Los Angeles County Sheriff's spokesman Steve Whitmore. 
 
 Ocean, 25, who is nominated for best new artist and best record for "Thinkin Bout You" at the Grammys in February, said on Twitter on Sunday night that he "got jumped by Chris and a couple guys." He said this resulted in a cut finger. 
 
 A representative for Brown has yet to comment. 
 
 The "Look at me Now" singer has attempted to rebuild his career and public image since 2009, but his entourage and that of Canadian rapper Drake were involved in a June 2012 brawl in a New York nightclub. No arrests or charges were brought in that case. 
 
 Brown and Ocean are both nominated in the best urban contemporary album category at the Grammys, which take place on February 10 in Los Angeles.

– Bad news for Chris Brown: Authorities tell Reuters that Frank Ocean wants Brown prosecuted over Sunday's parking spot brawl, and if charges are filed, Brown's probation in the Rihanna assault case could be revoked. Ocean—and witnesses—say Brown started the fight, but Brown apparently feels very much the victim in the situation: Yesterday he posted a picture of Jesus on the cross to Instagram and captioned it, "Painting the way I feel today. Focus on what matters!" TMZ has more details on the fight: A witness says Brown tried to shake Ocean's hand in the recording studio parking lot, but Ocean just laughed and refused, leading an angry Brown to punch him. The singers' respective "crews" got into an all-out melee, eventually ending up inside the studio and breaking "almost everything in the room," the source says. But Brown insists he didn't start the fight, and sources tell TMZ he's eager to tell police his side of the story.
