The Yorkshire Ripper’s murder spree is being turned into a Netflix show.
Bosses at the streaming giant hope it will follow the success of its documentaries on Madeleine McCann and US serial killer Ted Bundy.
Producers have visited relatives of some of the 13 women Peter Sutcliffe killed as well as survivors.
They will also speak to victims of crimes thought to have been committed by the monster – but which he was never convicted of.
A TV source said: “This will be a huge programme for Netflix and is likely to follow the same format as the Madeleine programme.

“It will focus on victims and the terrible impact of his attacks. It will also examine the dreadful police blunders around the case.
“Crucially, it will try to throw up fresh clues about crimes Sutcliffe has never been convicted of.
"That would help make it a smash hit in the UK and other countries like America and Australia, where he is a notorious name.”
A relative of one victim said: “They are speaking to a lot of people and going back over everything, treating it very seriously and also like a new investigation into him.”

Ex-lorry driver Sutcliffe, 72, used hammers, knives and screwdrivers to murder 13 women and tried to kill seven more from 1975 to 1980.
He is suspected of a string of other attacks, with West Yorkshire Police launching a cold case review in 2016.
