DJ Neil Fox has been arrested on suspicion of a further three sexual assaults.
The 53-year-old Magic presenter, known as Doctor Fox, said he "strenuously" denied the allegations after he was questioned at a London police station yesterday.
The broadcaster was quizzed by police as he answered bail over four separate alleged sexual assaults, for which he was arrested in September.
He now faces a total of seven allegations by five women and has been bailed to a date in March 2015.
Fox said he was "extremely upset" about the allegations and strenuously denied the assaults.
Two are alleged to have happened in the 1990s, while the third is said to have taken place in 2007.
