US singer Chris Brown has been arrested on suspicion of assault with a deadly weapon after a woman told police he had threatened her with a gun, the BBC reports.

Beauty queen Baylee Curran told the LA Times Mr Brown had pointed the gun at her face after she had been admiring his friend’s jewellery.

Mr Brown came out of his home after a stand-off with police on Tuesday.

The singer has several convictions for violence, including a 2009 assault on his then girlfriend, pop star Rihanna.

Police went to Mr Brown’s home following the emergency call early on Tuesday from Ms Curran, who by that time had left the property.

Ms Curran told the LA Times that she and a friend had gone to Mr Brown’s house with a business associate on Monday evening.

She said she had been admiring the diamond necklace of a man who had been showing off his jewellery when the man got angry and told her to back away.

That is when she says Mr Brown pulled out a gun, pointed it at her face and told her to get out.
