Jimmy Savile (left) was quizzed by detectives investigating the Yorkshire Ripper murders, a senior officer who worked on the inquiry said yesterday.
Former West Yorkshire Police detective John Stainthorpe said the disgraced presenter was a suspect in the notorious case more than 30 years ago.
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."
Mr Stainthorpe said the person who gave police the anonymous tip- off was "aiming in the right direction".
"Child perverts soon become child killers," he added.
Sutcliffe was convicted of murdering 13 women in 1981 and was sentenced to life imprisonment. He is held at Broadmoor and has been told he will never be freed.
He yesterday claimed Savile regularly visited and the pair became friends.
Rubbishing claims the late DJ abused around 300 victims over six decades, he said those making allegations were "jumping on the bandwagon".
