The radio DJ Neil Fox has been arrested over three alleged sexual assaults.
It comes two months after he was first arrested following four earlier allegations of sexual assault. He was detained on Monday when he returned to a police station on bail.
The new allegations involve different women. Two relate to events said to have happened in the 1990s, while the third dates from 2007.
Mr Fox said he “strenuously denies” the allegations and was “extremely upset”.
He has been bailed and is due to return to the police station in March 2015.
When Mr Fox was first arrested on 30 September, the Metropolitan Police said four allegations of sexual assault had been made.
Three of those allegations were described as historical but no time frame was given. One allegation was said to have taken place earlier this year.
Police also said they had searched properties in west London and the Littlehampton area of West Sussex as part of that investigation.
On Monday, Mr Fox said told ITV News: “[I’m] obviously extremely upset about these allegations. [I] strenuously deny these allegations.
“[I’ve been] with my legal team this afternoon trying to answer the police questions as best we possibly can, of course, and helping them as much as we can.”
Mr Fox, who uses the nicknames Dr Fox and Foxy, began his career in local radio before moving to Radio Luxembourg and then London’s Capital Radio in the late 1980s.
He presented various slots there and in 1993, landed the job of presenting the Sunday afternoon Network Chart Show, later known as the Pepsi chart.
His big TV break, which brought him to a wider audience, was as a judge on ITV talent show Pop Idol between 2001 and 2003 alongside Simon Cowell, Pete Waterman, and Nicki Chapman.
Mr Fox later appeared in the BBC Three sketch show The Wrong Door.
He left Capital in 2005 and joined Magic 105.4, where he presents the breakfast show, Foxy in the Morning. He is currently not hosting the show.
His arrest is not part of high-profile sex crime investigation Operation Yewtree, which was set up in the wake of revelations about BBC presenter Jimmy Savile.
