The singer was arrested outside the view of news helicopters that swirled overhead and throngs of camera crews gathered at the bottom of his hilltop estate. It marked the conclusion of a nearly 14-hour standoff and investigation.
Police spokesman Lt. Chris Ramirez said officers first responded to Brown's property in the Tarzana area of Los Angeles around 3 a.m. He did not identify the woman who called, elaborate on the assistance she needed, or know if she was injured.
Curran told the Times that she and her friend ran from the house and hid under an SUV as one of Brown's associates gave chase.
The model, who hasn't responded to requests for comment from The Associated Press, told TMZ she's visited Brown's home in the past and never encountered any trouble.
During the standoff that occurred while police awaited a search warrant, Brown later posted rambling messages on social media proclaiming his innocence and rebuffing reports that he barricaded himself in his "palace."
"Y'all gonna stop playing with me like I'm the villain out here, like I'm going crazy," he 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."
Brown's attorney, Mark Geragos, arrived at the house before police served the warrant and stayed on the property until Brown was transported for booking.
"Thanks to everyone for their support and well wishes. Chris is out and well. The allegations against him are demonstrably false," Geragos posted on Twitter after the singer posted bail.
The standoff and subsequent media attention provided a chaotic scene in typically quiet Tarzana as police closed off streets and rerouted traffic.
Throughout the afternoon, several of Brown's associates descended to the street below Brown's estate. They declined to identify themselves or answer questions from the media. In some instances, the men were belligerent, flashing obscene hand gestures and grabbing recording equipment.
In 2013, Brown struck a man outside a Washington, D.C., hotel and was charged with misdemeanor assault. The singer was ordered into rehab then dismissed from the facility for violating its rules.
Brown spent 2½ 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 was accused of throwing a brick at his mother's car following a counseling session. It came after Brown completed court-ordered anger management classes.
Brown's first single "Run It!" topped the charts in 2005. Since then, the singer and rapper has had a number of hit songs, including "Loyal" and "Kiss Kiss." He has also been a featured performer on several hits, such as Jordin Sparks' "No Air."
