Former
JLSmember has denied allegations he raped a fan in a hotel room after a gig.
Williams, 30, was arrested on 2 December, when police were called to a hotel room in Wolverhampton where he had been staying after a gig at the Gorgeous Club.
The West Midlands police report that a 20-year-old woman claimed she had been raped and sexually assaulted.
Another man, aged 29, was also arrested on suspicion of sexual assault.
Both men have been bailed until February, pending further inquiries, police said. In a statemnt, his representatives from 10 Worlds Music UK management said: "All we wish to say at this time is that Oritse denies the allegations against him.
"The matter is in the hands of the police and it would be totally wrong for us to comment any further."
The singer enjoyed pop stardom with the boyband JLS after appearing on the X-Factor in 2008. The band were together for six years before disbanding. Williams famously broke down in tears on the Alan Carr show Chatty Man whilst discussing the break-up.
