Authorities say officers responded to singer Chris Brown's Los Angeles home after a woman called police seeking assistance.
Police Lieutenant Chris Ramirez told reporters that the call came early on Tuesday from outside the residence in the Tarzana neighbourhood.
Officer Lyle Knight tells The Associated Press that police are waiting for a judge to approve a search warrant for the home in the San Fernando Valley area.
Multiple police vehicles are parked at the scene.
Calls to representatives for Brown were not immediately returned.
The Grammy-winning singer has had multiple run-ins with law enforcement. He spent six years on probation after pleading guilty to attacking his then-girlfriend Rihanna in 2009.
Activist and musician Ntsiki Mazwai did not bite her tongue on the matter.
She took to Twitter to voice her opinions about Chris, to the extent of calling the superstar a 'Nyaope boy' who has 'a sbotho look'.
Here are Ntsiki's Tweets:
