Pop star Chris Brown has been arrested on suspicion of assault with a deadly weapon after a standoff at his Los Angeles home.

Baylee Curran, a former beauty queen, told the LA Times that the singer had pointed a gun at her during a violent rage before she ran outside to call police.

Brown, 27, denied any wrongdoing in posts on social media before he was taken into custody and said he had woken up to find police outside the property.

Police said he will be arrested for assault with a deadly weapon.

Police who responded to the 911 emergency call at around 3am spent hours surrounding the home before obtaining a search warrant.

Before emerging from his home, Mr Brown posted videos online criticising the police action.

"When you get the warrant for whatever you need to do, you're going to walk right up in here and you're going to see nothing, you idiots," he said in one Instagram video, posted to 30 million followers.

Police said about half a dozen people had been escorted out of the residence after the stand-off ended and would be interviewed.

In 2009, Brown assaulted his then-girlfriend Rihanna, and in 2015 finished a lengthy term of probation, community service and domestic violenceclasses.
