Child killer Stuart Hazell allegedly rammed a sharpened object into the face of another prisoner during a frenzied attack behind bars.
Hazell was jailed for life after sexually assaulting and murdering 12-year-old Tia Sharpe, before stuffing her body into his girlfriend’s loft in New Addington, London, in 2012.
Now he is said to have attacked fellow convicted killer Omar Benguit, 45, stabbing him twice inside high security Wakefield Prison, West Yorkshire.
Benguit, who lost his right eye in a previous attack at another jail, was given urgent medical treatment at the prison after last month’s attack, according to the Mirror.
His sister Amy, from Dorset, alleges Benguit was attacked because he continues to deny the 2002 murder of student Jong Ok Shin in Bournemouth.
She said: ‘Omar didn’t do anything provocative. Hazel just ran at him and jumped on him and started hitting him with something in his hand.
‘Luckily he couldn’t get hold of a knife. It was a very nasty attack.

‘Some prisoners resent Omar because he absolutely maintains his innocence.’
A spokesman for the Prison Service confirmed two prisoners at HMP Wakefield were treated for minor injuries after an incident on August 31.
They also said an investigation into the incident was under way.
Hazell attacked Tia at her grandmother’s house while her family were out and then concealed her body in the loft.

He was later arrested and admitted the murder at the Old Bailey, where he was sentenced to life in prison with a minimum of 38 years behind bars.
The murdering paedophile, who was in a relationship with Tia’s grandmother and who was obsessed with pictures of child abuse, will not be up for parole until he is 75.
The house where Tia was murdered has since been demolished.
Her father, Steven Carter, has since said he ‘massively’ blames himself for his daughter’s death after his relationship with Tia’s mother turned sour.
Benguit who was jailed for the murder of Jong Ok Shin in Bournemouth in 2002.
It took two hung juries and three murder trials before Benguit was convicted in 2005.
The Court of Appeal has also dismissed two attempts to overturn the conviction.
Ms Shin, a South Korean language student, was stabbed three times while walking home after a night out.
Before she died, the 26-year-old told police in poor English her killer wore a mask and struck from behind.
Benguit was arrested more than a month after the murder but continues to deny involvement in the death.
Earlier this year a documentary re-examined the case and after looking at the evidence a TV jury decided Benguit was not guilty.
