Rapper Chris Brown Held On Suspicion Of Assault After Standoff

US singer Chris Brown has been arrested on suspicion of assault with a deadly weapon after a daylong standoff with police.

The rapper had refused to leave his LA home for several hours after a woman called 911 before dawn on Tuesday and reportedly claimed that he had pointed a gun at her face.

Baylee Curran said Brown and another man had become angry when she admired a diamond necklace - telling the LA Times she was chased out of the house and had to hide under a nearby car with a friend.

Brown had posted a series of videos on Instagram declaring his innocence - and in one clip, waved a cigarette around and declared that police would find nothing inside his home once they obtained a search warrant.

Police have since performed a lengthy search of his expansive home, and about six people have been escorted from the property for questioning.

In a statement outside the star's home, Lieutenant Chris Ramirez of the Los Angeles Police Department said: "He is being transported to robbery homicide, where he will be arrested for assault with a deadly weapon."

On Instagram, the rapper had denied reports that he had barricaded himself inside his house.

He also accused the police of "defacing my name and my character and my integrity" - and insisted he had done nothing wrong.

Brown has been in repeated legal trouble since he was convicted in 2009 for assaulting his then-girlfriend, Rihanna, which led to him spending six years on probation.

The Grammy-winning performer was forced to postpone a UK tour in 2010 after he was denied a visa, and was also refused entry into Canada six months ago.

In 2013, he was charged with assault after striking a man outside a hotel in Washington DC.

Brown was ordered to attend a rehabilitation centre as a result, but was then kicked out of the facility for breaking its rules.

After completing a series of court-ordered anger management classes, Brown was also accused of throwing a brick at his mother's car.

Last year, he was given 28 days to convince officials he should be given a visa for his Australian tour after the country's women's minister urged the government to refuse entry to Brown on grounds of "character".
