SARAH Payne's sadistic killer Roy Whiting was left covered in blood after being stabbed in jail.
The paedophile was attacked at HMP Wakefield - known as Monster Mansion - over the weekend.
It is understood Whiting was treated for minor injuries with police now investigating.
A source told the Mirror: "Whiting is hated in prison. He was stabbed and was covered in blood. They were trying to kill him."
Whiting was caged for life in 2002 after murdering eight-year-old Sarah.
The fiend snatched the youngster as she walked along a country lane to her grandparent’s home in Kingston Gorse, West Sussex.

Whiting has been subject to a string of attacks in prison since he was locked up.
In 2020, The Sun revealed how he was knifed by fellow lags you screamed "you f***ing n***e" at him.
The monster was also beaten by Richard Prendergast and Kevin Hyden, who both admitted Section 18 wounding with intent.
The pair had sneaked into Whiting's cell at the high security jail and attacked him before staff managed to intervene.

Sarah's murder horrified the nation after she was abducted following a game of hide and seek with her brothers in July 2000.
Her body lay undiscovered for 17 days in a field near Oulborough - around 15 miles from where she disappeared in Kingston Gorse.
A post mortem revealed she had been strangled and suffocated with most of her hair pulled out in the violent killing.
When police searched Whiting's van, they discovered sweets, toys and rope - as well as knives and baby oil.
Clothes officers seized were found to contain strands of Sarah's hair.
Whiting was convicted in December 2001 and is now serving at least 40 years for his sickening crimes.
