Yung Filly is arrested in Australia after being accused of sexual assault and rape

British YouTuber and rapper Yung Filly has been arrested over an alleged sexual assault in Australia.

Andres Felipe Valencia Barrientos, 29, was arrested in Brisbane on Tuesday and extradited to Perth on Wednesday.

He is accused of sexually assaulting a woman in her 20s at his Perth hotel on September 28 after performing at Bar1 nightclub in Hillarys on the evening of September 27.

The rapper, who has more than three million followers on Instagram, had performed at Havana Nightclub on the Gold Coast two days before his arrest.

He is charged with four counts of sexual penetration without consent, three counts of assault and one count of obstructing a person's normal breathing or circulation by applying pressure to the neck.

Mr Barrientos will face Perth Magistrates Court on Thursday.

The event at Bar1, where Mr Barrientos performed before the alleged attack, marketed the British rapper's performance as the “ultimate evening escapade”.

“The event promises to be a seamless blend of spontaneity, humor and music that will have you talking for weeks!” said MoshTix.
