Bowers, the ex-boyfriend of glamor model Katie Price, was arrested as his 35-year-old friend was questioned on the same suspicion. The alleged attack occurred just hours after Bowers headlined a DJ set at the Deco Lounge nightclub in nearby Hertford.
"A 32-year-old man from Surrey presented himself at Hatfield police station by prior arrangement on April 3," a Hertfordshire police spokesperson said in a statement. "The man has been arrested and is assisting police following an allegation of sexual assault."
According to The Daily Mail, both Bowers and his unidentified friend are denying the allegations, and were released on bail until May 14.
