Chris Brown & Police in standoff at his home after lady claims that he threatened her with a gun at his home

Long story short...some lady reported that Chris Brown pulled a gun on her at his home. The police have surrounded Chris' home, with helicopters flying around his house. They claim he barricaded himself at his home and refused to surrender. The stand-off has been going on for hours now. Chris has refused to leave his home and without a search warrant or Chris' permission, the police can't enter his house. A SWAT team has arrived his home. Read how TMZ is reporting the whole drama below...

Chris Brown is a suspect in a criminal assault investigation after a woman called 911 and told cops ... he threatened her with a gun ... TMZ has learned. The alleged incident went down early Tuesday morning in L.A. We're told Chris and the woman were in a home when she claims they argued and he pulled the gun.

The woman called 911 and police responded and took a report. We're told the case is under investigation and Chris is the sole suspect.

7:55 AM PT -- TMZ has learned Chris was in the house with several friends, including Ray J. They were talking and at one point Ray was getting a tattoo when some "uninvited guests" appeared inside the house and were asked to leave.
At that point, the story gets murky. The guests included a man who was invited, and two women who were not -- one of the women who'd been asked to leave is the one who made the police report, claiming Brown pulled the gun on her. Someone inside the house insists Chris was asleep the whole time.
At some point Ray J left the house and when he got to the base of the driveway, police handcuffed him and seized his BMW. They checked his ID, uncuffed him and let him go, but kept his car as evidence. He Ubered home.
At the time of this post, Chris is still in the house. He never left. Police are knocking on the door, but no one inside is responding. We don't know what police will do if he tries to leave.

 8:45 AM PT -- We've learned the SWAT team is on its way to Chris' home and the LAPD is in the process of obtaining a search warrant. We're told cops want to see if a gun matching the description from the woman is in the house. As of now, Chris has not left his residence.

9:20 AM PT -- Chris is finally awake and posting videos. He's pissed about the police presence at his house and feels he's being harassed. He even dropped a "F*** tha police!"
The cops are still outside.

9:40 AM PT -- Police say they are still trying to make contact with Chris.


Update 2

The woman who called the cops on Chris Brown says the singer pulled a gun on her because she was admiring a piece of jewelry ... and afterwards his people demanded she sign a non-disclosure agreement.

Baylee Curran appeared on "TMZ Live" and said she had partied with Chris in the past and he was always nice, but this time he appeared to be out of it ... on drugs or alcohol.

She says she came to his house with a friend, spent a little time in the hot tub, and then walked back inside where a member of Chris' crew was displaying a piece of jewelry. Baylee says when she admired it the guy went nuts, and then Chris followed suit by demanding she "get the f*** out" and pointed a gun at her.

The craziest part ... as she tried to leave she says Chris' people wouldn't let her take her cell phone until she signed a non-disclosure agreement. She refused to sign, and she and her friend left.

TMZ broke the story ... Baylee, Miss California Regional 2016, called 911 and that started the standoff with Chris. 

Law enforcement sources tell us Chris is about to get arrested.
