Chris Brown has been arrested on suspicion of assault with a deadly weapon after a prolonged, 11-hour stand-off with the police at his $4million mansion.

Baylee Curran, a former Miss California Regional 2016, called 911 at around 3am on Tuesday claiming Brown had pointed a gun at her after she admired his friend's jewelry, TMZ reported.

Police arrived at Brown's sprawling estate in Los Angeles, but no one answered the door and it took hours before they obtained a warrant to search the home for a weapon.

Emerging from his mansion around 2.43pm (PT), Brown took off his sweatshirt and sat on the ground in front of the door, appearing relaxed before he went back inside around 3pm (PT).

Authorities said Brown was cooperating with the Los Angeles Police Department before he was seen in the backseat of a car being taken into custody around 5pm (PT).

LAPD Robbery-Homicide Division detectives searched the property, while Brown's entourage of about half a dozen people were patted down and interviewed by authorities.

'We're getting the cooperation of everyone that came out,' LAPD Lt. Chris Ramirez said

Brown is being taken to downtown Los Angeles where he will be formally booked on Tuesday night or Wednesday morning, police said.

A felony assault with a deadly weapon conviction carries a sentence of four years in county jail, along with a $10,000 fine.

Because Brown pleaded guilty to the felony assault case involving ex-girlfriend and pop singer Rihanna, he was forbidden to possess a firearm under California law.

Authorities would not say if they found a weapon on the property and would not comment on the accusation that the singer threw a bag out of a window with a gun and drugs inside.

During the standoff, the Grammy award winning singer posted a series of Instagram videos ranting about police harassment (pictured)

In a radio interview, Curran said she arrived at Brown's house for a 'go-see', or audition for a music video appearance (pictured, one of the singer's friends leaving his estate)

She and a friend had spent time in his hot tub, but when she walked back into the house and admired a diamond cross necklace on one of his friends, an argument broke out (pictured, Brown's friend leaving the home)

Brown was wearing a white t-shirt and a red baseball cap when he emerged earlier this afternoon and sat on the ground outside his house as officers stood nearby.

The singer appeared calm before he went back into the home about 15 minutes later.

Police interviewed about half a dozen people who were inside his home, and LAPD Lt. Chris Ramirez said: 'We're getting the cooperation of everyone that came out.'

Brown's attorney Mark Geragos arrived at the home and later told The Los Angeles Times the singer denied any wrong doing.

Curran (above) shared a video of herself to Instagram in the afternoon before deleting it. She said: 'Do you all honestly think I wanted this, that I caused this? If somebody put a gun to your head what would you do? Call the police?'

LAPD Deputy Chief Bob Green had described the standoff between Brown and officers as 'long and protracted.'

Curran, who is an aspiring actress, shared a video of herself to Instagram in the afternoon before deleting it.

'Do you all honestly think I wanted this, that I caused this?' Curran asks in the video.

'If somebody put a gun to your head what would you do? Call the police?'

During an interview on the Australian radio show KIIS 101.1 with Matt Tilley and Meshel Laurie, Curran said she was 'shocked' to have been embroiled in the incident.

The former beauty queen said she arrived at Brown's house for a 'go-see', or audition surrounding an appearance for a music video.

She and a friend had spent time in his hot tub and walked back into the house when one of Browns' friends was showing off a piece of jewelry.

Curran (above) claims that when she tried to leave the property, Brown's people would not let her take her phone with her unless she signed a non-disclosure agreement. She did not sign it and left with her friend before calling 911

Curran (above), who is a professional equestrian, alleged that Brown appeared to be 'on drugs or alcohol'

Curran told Matt & Meshel she was admiring a diamond cross necklace, but never touched the jewelry when another man nudged her in the shoulder and warned her to step away.

'And then that’s when Chris pulled a gun and said: "Get the f*** out. Like, I’ve had enough of you girls, haven’t I told you girls enough,"' she told the radio show hosts.

Curran, who is a professional equestrian, appeared on 'TMZ Live' claiming she had partied with the Loyal hit-maker in the past without a problem.

She also alleged that Brown appeared to be 'on drugs or alcohol' during the incident on Tuesday, TMZ reported.

Curran claims that when she tried to leave the property, Brown's people would not let her take her phone with her unless she signed a non-disclosure agreement.

But Curran refused to sign it and left the house with her friend and they called 911.

Officers entered the property with a search warrant in the afternoon, after Brown and his entourage failed to respond to repeated requests to open the door.

In Brown's multiple Instagram posts he said he had just woken up to the sound of circling helicopters, and was 'too tired' to be dealing with police

A spokesman for the LAPD confirmed to DailyMail.com that police were first summoned by a woman requesting assistance.

When officers surrounded the property on Tuesday morning, the 27-year-old shouted 'come and get me' and allegedly threw a bag containing drugs, a gun and other weapons out the window, TMZ reported.

During the standoff, the Grammy award winning singer posted a series of Instagram videos ranting about police harassment.

He said he had woken up to the sound of circling helicopters, and was 'too tired' to be dealing with police.

'So I'm sleep half the damn night,' he told the camera. 'I just wake up. All these mother***ing helicopter choppers is around. Police out there at the gate.

'Come on my n****! What the f*** hell else do you want from me?

'I stay out the way, take care of my daughter, do work. I don't f*** ugly b**ches, trifling b**ches, whatever else.'

Brown accused the police of over-reacting, and said: 'I'm way too tired to be dealing with this bulls***.

'Every three months you come up with something. What's gonna be next?

'At the same time when I call the police for stalker people that are endangering my life, they don't come 'til the next day.

'Let somebody make a f***ed up allegation about me, and "oh yeah the whole f***ing swat team".

'I don't care. Y'all gonna stop playing with me like I'm the villain out here, like I'm going crazy.

'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.'

Leaving the property: An unknown woman is walked off the scene by an officer; it is not known if she was involved in the incident which sparked the stand-off

Waiting: Brown told officers to 'come and get me' in an Instagram video as they surrounded his property

Along with plugging his new track and referring to the Black Lives Matter movement in the rambling videos, he also stated that the media were blowing the stand-off out of proportion.

''Barricaded myself in my house?' Have you seen my house! Imma barricade myself in a palace! 'I'm not coming out!' But what?

'I ain't did s***. I ain't gonna do s***!

'You idiots. I'm tired of f**ing with it all. You're the worse gang in the world, the police. And I said it. F*** you.'

Earlier in the day a large group of friends, including both Brown and Kim Kardashian's infamous ex Ray J, were socializing at the property when another guest arrived with two women - one of them reportedly Curran.

While the man was invited, the women were not, sparking a disagreement between them and Brown, TMZ reported.

Escalating: The incident grew increasingly hostile, after Brown took to Instagram

Armed: Officers were on scene from 3am, saying they wanted to 'talk' to Brown

However sources told Fox 11 that the women instead claimed to have been invited inside.

'We're trying to make contact with the residents here in Tarzana,' an officer told reporters outside the home.

'They've been uncooperative so we're working to obtain a search warrant.'

And he added: 'We need their co-operation in order to deal with this in a peaceful manner.'

Ray J - who was said to have been getting a tattoo when the disagreement first occurred - left the property before 7am.

His BMW was impounded by police as evidence, leaving the younger brother of singer Brandy to take an Uber home.

Ray J took to his Instagram and shared a video discussing the incident in the afternoon on Tuesday.

'Yo it's Ray J, check it out. I'm real upset about today,' he said.

'I'm not happy with how things are handled and how people can take a false story and blow it up into something way more than what it should be.

'You got just positive people around and you look outside and it's like a war zone for no reason.

'For somebody some what stranger said about something that don't got nothing to do with nothing and to react like that so fast without knowing the facts and knowing what's up ain't cool.

'It's just not right, it shouldn't be like this. I support the homie Chris, I support the whole movement.

'I'm here and again, man s*** got to change, it can't be like this every time somebody yippity yap (sic) trying to get an extra buck and it turns around and it's all bad on us. It ain't cool.'

The Love and Hip Hop Hollywood star captioned the post and wrote: 'Thingz (sic) gotta (sic) change man! This ain't kool! (sic) - much support to @chrisbrownofficial and the whole team! #StayPositive #DontLetTheDevilWin'

An unidentified woman dressed in a denim shirt and high heels, was seen leaving the property with a police escort around 11am.

911 call: The investigation is ongoing and several police cars can be seen outside the mansion

Co-operating: Brown's friends emerged from the home one by one, and were searched by police as cameras watched

At 11.30am a man, not thought to be Brown, emerged from the property and was seen co-operating with officers, who searched him.

Aerial views of the scene taken throughout the morning and afternoon showed multiple police officers on the perimeter of the property, along with what appeared to be a deflated bounce house on the grounds.

Brown has had a number of run-ins with the law in recent years, beginning with his conviction for assaulting then-girlfriend Rihanna in February 2009.

For that offence, he was sentenced to five years of probation, one year of domestic violence counselling, and six months of community service, and his probation was finally lifted in March 2015.

In 2014, he spent almost three months in jail last year for violating his probation after allegedly hitting a man in Washington, D.C.

Brown had his probation revoked in January 2015 following a poor report which claimed he had a 'knack' for finding trouble and had been present at two shootings, though he was not involved in either.

Notes at the time read: 'There is also concern that when he performs or attends at some of his public events, people will get shot or seriously injured.'

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.

Father: Brown is the parent of two-year-old daughter Royalty, with former lover Nia Guzman

Then in June of this year, the She Ain't You hit-maker was accused of stomping on a man's head during a club appearance at the Cannes Film Festival.

Police are also reported to have been called to Brown's property at least five times this year, in response to complaints of disturbance of the peace.

Meanwhile, the Fine China singer's former lover Nia Guzman previously claimed he was unfit to care for their child without strict supervision and asked a court to appoint a monitor and reduce the amount of time the star was allowed to spend with the little girl.

However, in May, a judge denied the request and kept the existing arrangement for joint legal and physical custody - which sees Chris care for his two-year-old daughter Royalty 12 days a month - of the youngster in place.
