Pop star Chris Brown has been arrested at his home following a tense 11-hour stand-off with police, authorities have confirmed.
The singer was held on suspicion of assault with a deadly weapon, Los Angeles Police said.
LAPD Lieutenant Chris Ramirez said: "He is being transported to robbery homicide, where he will be arrested for assault with a deadly weapon."
Ramirez declined to elaborate on the charges against Brown, saying that the investigation was still under way.
Officers surrounded the singer's home on Tuesday following a pre-dawn 911 call from a woman - later named as beauty queen Baylee Curran - who claimed he had pointed a gun at her.
Brown, 27, denies any wrongdoing and said on Instagram posts that he had woken up to find police outside and that they would need a warrant to enter the Tarzana property.
Lieutenant Ramirez said earlier: "This morning, around three o'clock, officers responded to a radio call for a woman requiring assistance.
"The incident involved the residence of Mr Chris Brown, where officers responded and met with that person."
Police spent hours waiting outside Brown's home before obtaining a search warrant and beginning a search of the sprawling premises in the early afternoon.
The singer's entourage began to emerge at around 12:40pm, before they were interviewed by police.
The singer himself followed two hours later, leaving the building at around 2:38pm wearing a white t-shirt, black jeans and a red hat.
He looked in good spirits as he spoke to law enforcement and a second person, believed to be his lawyer Mark Geragos.
It was reported on Tuesday by TMZ that the singer was being investigated on an allegation of criminal assault, after Curran claimed he threatened her with a gun while at an LA residence, prompting her to call 911.
Soon after images of police outside Brown's house were posted to social media, with the singer then insisting he had done nothing wrong in an expletive laden Instagram video.
The woman at the centre of the drama was quickly identified as beauty queen Curran.
On Monday night she claims to have gone to his Tarzana mansion where they hung out in a hot tub and were having fun, until she admired a piece of jewellery worn by a member of Brown's crew.
Brown's team have yet to comment publicly on events.
