An incarcerated paedophile who boasted about his sick crimes was subsequently disembowelled by fellow inmates.

Mitchell Harrison was killed at high-security Frankland Prison, in County Durham – the same institution where Soham killer Ian Huntley was slashed in the throat by a fellow inmate last year.

The 23-year-old serial sex attacker Harrison was slashed at with homemade weapons, thought to be razor blades melted into toothbrush handles.

Two fellow inmates were said to have eaten breakfast together before turning themselves in after guards came across the grisly scene.

Detective Chief Inspector Steve Chapman, of Durham Police, said a pathologist found Harrison had died of ‘multiple injuries’.

Criminology expert Professor David Wilson, of Birmingham

City University, said the extremely violent nature of the attack was


He said: "If you are disembowelling somebody you are defiling their

body. It is what you might call “ritualistic slaughter”. The question

is how can something like this take place in Frankland and why didn’t

the staff protect him?"

The Ministry of Justice said the incident was a matter for police.

Harrison was jailed indefinitely at Carlisle Crown Court in January last year after a judge said he posed a ‘substantial risk’ to young girls.

The manipulative sex pest lured his teenage victim to his flat in Kendal, Cumbria. Once inside he ordered her to strip before raping her twice.

It was the third time Harrison had been in trouble for sexually assaulting girls.

At only 13 he was given a formal warning for indecently assaulting a seven-year-old and when he was 15 he was taken to court for threatening to rape a 15-year-old classmate.
