Jimmy Savile was quizzed by detectives investigating the Yorkshire Ripper murders, a senior officer who worked on the inquiry says.
Former West Yorkshire Police detective John Stainthorpe said the disgraced presenter was a suspect in the notorious case more than 30 years ago.
Yorkshire Ripper Peter Sutcliffe has jumped to the defence of Savile, who he claims is innocent and befriended him during visits to Broadmoor high security hospital.
Mr Stainthorpe, who spent 40 years in the force, told ITV's Calendar News: "When the Ripper was really active, one of the suspects put forward by the public was, in fact, Jimmy Savile.
"Obviously, it was not he, but he was interviewed along with many others."
