Frank Ocean, the R&B singer and songwriter, wants to press charges against Chris Brown after the two were said to have fought over a parking spot near a Los Angeles recording studio, a move that could jeopardize Mr. Brown’s probation on a previous assault conviction, Reuters reported. Mr. Brown pleaded guilty to assaulting Rihanna in 2009.

The altercation with Mr. Ocean was reported to have taken place on Sunday outside the Westlake Recording Studios in West Hollywood. Though no charges had been filed as of Tuesday morning, Steve Whitmore, a spokesman for the Los Angeles County Sheriff’s Department, said Mr. Ocean “is desirous of prosecution in this incident.” Both men are nominated in the Best Urban Contemporary Album category at the Grammy Awards, which will take place on Feb. 10 in Los Angeles.
