Police allege Vlado Blazevski and two other men took cash, a mobile phone, neck chain, an ATM card and keys from a man on Tuesday night after they forced him into a car and demanded $2000 and $6000 from him.

St George police said the man was assaulted before he escaped and called for help.

Police also arrested Mr Blazevski, John Youssef, 31, of Allawah, and Carlito Rizo, 27, of Bexley.

They were charged with detaining a person for advantage and robbery.

Mr Rizo did not apply for bail and will face Central Local Court on December 10.

Mr Youssef will have a bail hearing in Central Local Court next month.

Sex assault charge

A WOMAN agreed to have sex with a man accused of sexually assaulting her at the Ivy nightclub, George Street, Sydney, his lawyer told a court on Saturday.

Chris Corben, 30, of Lilli Pilli, is accused of sexually assaulting a 34-year-old woman in the bathroom of the nightclub at 2am on Friday.

His lawyer, Mitchell Cavanagh, told Parramatta Bail Court that the alleged incident took place for 30 minutes and was not forced. He told the court that the woman and Mr Corben were naked at the time.

``It would be difficult to detain another person while removing their clothes and one's own clothing,'' he said.

Magistrate George Zdenkowski noted that police prosecutors did not oppose bail and granted "very strict conditional bail'' of $10,000.

Mr Corben must surrender his passport and report to police daily.

He was ordered not to consume alcohol or enter a licensed premises and was forbidden to have any contact with his alleged victim.

"This is an extremely serious offence,'' Mr Zdenkowski said. "There are a number of issues. The primary concern is the participation of the victim.''

Mr Corben is due to face Central Local Court on January14.
