Frank Ocean is pressing charges against Chris Brown over an alleged assault during a dispute over a parking spot.
Brown is accused of punching Ocean in a brawl outside Westlake Recording Studios in Los Angeles, officials told the Los Angeles Times.
"Of course, we are going to investigate," sheriff's spokesman Steve Whitmore said. "It is our understanding it does not rise to the level of an alleged assault. As a matter of fact, it could be a minor scuffle over a parking spot.
"Chris Brown is a named suspect in a battery report," he continued. "The victim is desirous of prosecution."
Brown is already on probation for assaulting his then-girlfriend Rihanna before the Grammy Awards in 2009.
