Authorities responded to singer Chris Brown's Los Angeles home early Tuesday after a woman called police seeking assistance, officials said.
The call came in around 3 a.m., from outside the sprawling hillside property in the Tarzana neighborhood, police Lt. Chris Ramirez told reporters at the scene. Ramirez didn't say what assistance the woman needed.
"Detectives are trying to make contact with Mr. Brown," Ramirez said. They also want to talk with the woman and any witnesses, he said.
Police were waiting for a judge to approve a search warrant for the home in the San Fernando Valley area, Officer Lyle Knight told The Associated Press.
Meanwhile, Brown posted a least three online videos declaring his innocence and dismissing TV reports that he was barricaded inside.
"I don't care. Y'all gonna stop playing with me like I'm the villain out here, like I'm going crazy," Brown said in one Instagram video, waving a cigarette and looking at the camera. "When you get the warrant or whatever you need to do you're going to walk right up in here and you're going to see nothing. You idiots."
Several police cars were parked at the scene.
Brown, who won a Grammy for his 2011 album "F.A.M.E.," has been in repeated legal trouble since his felony conviction in the 2009 assault of his then-girlfriend Rihanna. After several missteps, he completed his probation in that case last year.
In 2013, Brown struck a man outside a Washington hotel and was charged with misdemeanor assault. The singer was ordered into rehab but was dismissed from the facility for violating its rules. He spent two and a half months in custody, with U.S. marshals shuttling him between Los Angeles and the nation's capital for court hearings.
In another incident while in treatment, Brown allegedly threw a brick at his mother's car following a counseling session. This was after Brown had completed court-ordered anger management classes.
In January, a Las Vegas woman alleged that Brown hit her and took her cellphone. Police investigated but did not find evidence to file charges.
