Black cab rapist John Worboys has been working in a prison healthcare department helping unwell lags.

It was ruled this week the predator was still considered too dangerous to be released and was refused parole for the second time.

A report revealed he has admitted to attacking 90 women and had been praised for his 'willingness' to work.

The 68-year-old monster is thought to assist with education and provide help and support to unwell or elderly prisoners in his role.

A Parole report into his time in prison said: 'Mr Worboys' behaviour in prison has been of a high standard with only one relatively minor negative IEP warning in 2010 and no adjudications.

'There have been positive NOMIS entries in respect of his work ethic and attitude. He is described as compliant, engages with his case management team and works in the Health Care Department.

'The Prison Offender Manager speaks positively of his behaviour in prison praising his willingness to undertake tasks.'

The report - which was praised by Carrie Johnson who is believed to be Worboys' youngest victim - also made clear the cab driver accepts he attacked 90 women.

In a section about unproven offending, it said: 'Whilst we have not heard from Mr Worboys on the issue, the prisoner- commissioned psychologist in her report dated August 2019, refers to his acceptance of 90 victims.'

The parole board said he claimed to feel 'enormous regret, remorse and shame' towards 'the women he has harmed and their families and friends'.

Worboys was first convicted in 2009 of 19 sexual offences linked to attacks on 12 women between October 2006 and February 2008. 

The 68-year-old, now known as John Radford, stalked London's West End in a cab before offering his victims sedative-laced champagne and attacking them.

He lured women into his cab late at night, pretending to have won the lottery before asking them to help celebrate his winnings to make him appear more interesting.

Worboys told psychiatrists he had been 'fantasising' about his crimes since 1986, and was motivated by 'hostility towards women'.

He was able to continue offending due to a string of police mistakes after 10 women reported very similar allegations between 2002 and 2008.

In 2009, he was jailed indefinitely, with a minimum term of eight years for 19 sex attacks on 12 women.

He was cleared for release by the Parole Board after 10 years without his victims being informed. Officials had failed to take into account evidence he had attacked 105 women.

But a decision to release Worboys in 2018 was reversed by the Parole Board after widespread public outrage which sparked other victims to come forward.

In 2019, he was sentenced to life with a minimum term of six years after more victims came forward.

The serial sex offender made a fresh bid for freedom during a closed-doors hearing this week, despite pleas from his victims to hold it in public.

The coward had moaned that being scrutinised in public would prevent him from giving proper evidence.

Reacting to the news, Carrie Johnson, the wife of former Prime Minister Boris Johnson, said: 'It has been a hugely anxious wait knowing that Worboys was up for parole again.

'The relief I feel hearing that he will remain behind bars is hard to put into words. Women and girls across Britain are safer as a result of this decision.'

The Parole Board did not direct his release or recommend a move to open conditions, she said.

Mrs Johnson, 38, is believed to have been the prolific sex offender's youngest target when he picked her up after a night out on the King's Road and plied her with spiked vodka.

The media consultant and charity advisor, who has four children with the former Conservative Prime Minister, was in her first year at Warwick University when the terrifying incident took place.

She was waiting at a bus stop when Worboys offered to take her home for just £5, professing to live just around the corner.

He proceeded to tell her that he had won some money at a casino and offered her a glass of champagne to celebrate, which she promptly poured away when he wasn't looking.

He then stopped the cab under the pretence of needing to go to the toilet and was gone for 10 minutes, which Mrs Johnson later realised was him stalling for the drugs to kick in.

When he realised that they hadn't, he pressured her into having a shot of vodka, which she begrudgingly agreed to.

She made it home and then collapsed 'like a rag doll' in front of her mother, then 'crawled into the bathroom and became very sick,' with her 'head spinning so much that I told my mother I wanted to die.'

It wasn't until six months later, when Mrs Johnson read that a black cab driver had been arrested, accused of raping numerous women that she 'froze' and 'knew it was him.'

Mrs Johnson was one of nearly 100 women who came forward to the police and one of 14 who was selected to go to court to testify, deciding to waive her anonymity.

Sarah, a victim of Worboys, whose name has been changed to protect her identity, said: 'Thank goodness the right decision has been made and the parole board have recognised what a danger he is.

'We can all sleep lighter knowing he is still behind bars.'

Worboys' crimes have been portrayed in Believe Me, a new four-part series on ITV, starring Daniel Mays and Miriam Petche.
