The Los Angeles County Sheriff's Department confirmed receiving a call about six men fighting over a parking space, the Associated Press reported. The fight scene had dispersed by the time police arrived.
Though police did not name Ocean in the statement, Brown was listed as a suspect. "The altercation allegedly led to Chris Brown punching the victim," the police said in a statement.
In a Sunday night post on Twitter, Ocean accused Brown of assault. "got jumped by chris and a couple guys. lol. I only wish everest was there," he said. Everest is Ocean's Bernese Mountain dog.Ocean added that injuries sustained in the altercation will affect his upcoming Grammy performance. "cut my finger now I can't play w two hands at the grammys," he added via Twitter.
According to reports from TMZ, the confrontation occurred as Brown attempted to exit Westlake Studio after listening to music from an artist with whom he works.
When Brown was walking out, "Frank Ocean and his crew blocked Chris from leaving," Brown's associates told TMZ. Ocean is accused of saying, "This is my studio, this is my parking spot."
A member of Ocean's entourage attacked Brown after the "Forever" singer attempted to shake Ocean's hand, sources told TMZ. One of Brown's friends intervened, hitting Ocean's associate, TMZ reported.
Individuals associated with Brown claim that Ocean charged at Brown. Brown reportedly retaliated by pushing Ocean and a fight ensued.
When police arrived, Brown had reportedly left the scene, however, authorities were said to have spoken to Ocean.
In 2011, the R&B singers were involved in a feud via Twitter.
If Ocean's cut to his hand does affect his Grammy performance, it would be the second time one of Brown's violent incidents impacted the music award show. As a result of Brown's 2009 felony assault on Rihanna that occurred on the eve of the event, both artists cancelled their scheduled performances.
Brown has also had other outbursts since. Last March, following an interview on Good Morning America, he had a meltdown and was accused of throwing a chair into a window in his dressing room. And in June, he and rap star Drake and their entourages fought in a New York nightclub. In the latter, bottles were thrown resulting in San Antonio Spurs player Tony Parker being injured by shattered glass cutting his eye.
Representatives for Brown and Ocean did not immediately respond to Yahoo! Music's request for comment.
