BLACK cab serial rapist John Worboys will remain in jail after the Parole Board reversed its decision that he should be released.

The board had ruled in January that it was safe for Mr Worboys, who now goes by the name John Radford, to be freed after less than 10 years behind bars. He was jailed indefinitely in 2009, having been found guilty of 19 offences.

A Parole Board spokeswoman said today: "Under current legislation, Mr Worboys will be eligible for a further review within two years. The date of the next review will be set by the Ministry of Justice.”

The board examined a 1,255-page dossier on the serial sex offender and listed risk factors including “sexual preoccupation, a sense of sexual entitlement, his attitudes towards women and a belief that rape is acceptable.”

It was also said that Mr Worboys felt a need to have sexual contact with women and to control them.

London Mayor Sadiq Khan welcomed the decision and said he hoped it would provide reassurance to victims.

“Ensuring victims are put at the heart of our justice system is crucial. There must be an urgent overhaul of how decisions to release offenders are taken,” he said.

The Parole Board assesses whether serving prisoners in England and Wales are safe to be released into the community or moved to open prisons, considering around 25,000 cases a year.

In March, the board’s direction to release Mr Worboys was quashed by the High Court following a legal challenge by two women, resulting in Mr Worboys remaining behind bars until the case was reassessed.

The End Violence Against Women Coalition said it was an important victory for women who challenged the first “poor decision.”

A spokesperson for the campaign group said: “Survivors of Worboys were failed repeatedly by the justice system and had to fight for justice at every stage.

“This country needs a justice system which works to prevent and deliver justice on rape. We still have a long way to go.

“From start to finish, the justice system fails to tackle sexual violence. That's why we’re calling for an end-to-end independent review to establish the barriers to justice — from who reports to what happens at the end of a sentence.”
