The former detective who exposed Jimmy Savile in an ITV documentary has told Radio 5 live Breakfast that there will be arrests of people of "significant standing".
Mark Williams-Thomas also said he thought there could be as many as 500 victims.
Last week the Metropolitan Police said its inquiry into the Jimmy Savile allegations had become a formal criminal investigation involving living suspects and the decision not to prosecute the presenter in 2009 is being examined by the Director of Public Prosecutions office.
