A spokesman said: “Enquiries by officers from the Child Abuse and Sexual Offences Command are ongoing.”Worboys was given an indeterminate prison sentence when he was convicted in 2009 and told he must serve a minimum eight years in jail. He was convicted of one rape, five sexual assaults and 12 charges of drugging women. “If his legal representative said it is not reasonable then that argument would normally go back to the original parole Board panel.”The Telegraph understands the original plan was for Worboys to live in a bail hostel in London where it was felt authorities could keep a closer watch on him, not least for his own protection.A Parole Board spokesman said: “The Parole Board is required to ensure all conditions are necessary and proportionate, while protecting the public and victims.”As a party to the parole process, all offenders have the legal right to make representations as to their licence conditions, but the ultimate decision rests with the Parole Board – which will always prioritise public protection.” John Worboys will be asked if he objects to wearing an electronic tag when he is eventually released from prison.Worboys, 60, dubbed the ‘black cab rapist’, was due to be freed at the end of last month after being granted parole. The Telegraph has learnt that the original conditions for Worboys’ release allowed him to live in London and without an electronic tag. The Parole Board judged him no longer a risk to the public at a hearing in December despite complaints that he drugged and sexually assaulted more than 100 women while working as a London taxi driver.Victims have now protested to the Parole Board about the terms of his release. They are demanding he is tagged and is banned from London where most of his victims live.But Worboys must be asked whether he objects before more stringent conditions can be put in place. His lawyers can contest tougher licencing on the basis that nothing about his circumstances have changed since the Parole Board first agreed them. John Worboys, in his days working as a stripper before becoming a black cab driver The hearing will pave the way for a full-blown legal review, probably within a fortnight. If the victims lose the case Worboys will then be eligible for release by the end of February, a month later than originally planned. Victims hoping to keep Worboys, a former stripper, in jail will hope that – should the judicial review fail – police and prosecutors can bring further charges against him.The solicitor for the two women bringing the review has passed details of five new victims to the Metropolitan Police. Harriet Wistrich, of law firm Birnberg Peirce, said: “We have passed five new cases on to the police which have never been investigated. We have also asked police to look at cases that were investigated at the time but not prosecuted with a view to new prosecutions.” Ms Wistrich added: “It’s incredibly brave of them. Obviously no one wants to really dig all this stuff up again. All these cases have striking similarities to the cases publicised.”The earliest of the fresh complaints dates back to 1999.Scotland Yard is already actively looking at one fresh allegation. A spokesman said the force could not comment on the extra cases referred by Ms Wistrich.

They [victims] have gone for additional requests. Worboys will now be asked: ‘do you want to be tagged or would you be against being tagged’. Two victims have lodged a judicial review of the decision to release Worboys, one of Britain’s most prolific sex offenders. The High Court is expected at a hearing on Wednesday February 7 to agree to disclose all material in the case.Lawyers for the two women will need to persuade the court that Worboys’ release was irrational because of the danger they insist he still poses.The parole Board is standing by its decision but will not contest the disclosure of documents that led to granting parole to Worboys.
