A PRISON officer left scarred after a Kendal paedophile was disembowelled in front of his eyes has won a £125,000 payout.

Alan Johnson, 59, was working at HMP Frankland, Durham, when he witnessed the horrific attack on convicted paedophile Mitchell Harrison.

The 23-year-old was serving an indeterminate sentence of at least four-and-a-half years after he raped a teenager.

In August 2009, when he was 20, he lured the 13-year-old girl to a flat in Kendal where he raped her twice before she escaped by running into the street.

By that time he already had a criminal record, having been given an official warning in 2001 for indecently assaulting a seven-year-old girl.

Police at the time described Harrison as a “brutal offender” who had carried out a “violent, cruel attack on a defenceless 13-year-old girl”.

In 2011, lifers Michael Parr and Nathan Mann, cut his neck with a plastic scalpel and opened up his stomach.

Reports at the time said the pair were cannibal fantasists and planned to eat Harrison.

Mr Johnson was first on the scene and despite the events worked the rest of his shift.

Following the incident, he said he suffered from flashbacks, anxiety, lost sleep and depression.

He also was diagnosed with post-traumatic stress disorder (PTSD) as a result of his involvement in the incident.

At a North Shields tribunal, Mr Johnson won a claim for harassment while trying to return to work – a payout is to be announced.

He won a £125,000 settlement in an earlier claim against the prison service.
