LONDON — The Parole Board refused to grant parole to convicted sex offender John Worboys last week in London, ruling that he should remain in prison. Worboys will next be considered for parole in about two years.

The Parole Board said Worboys "continues to represent a high risk of committing further serious sexual offences against women." Worboys is serving a life sentence after drugging women in his taxi by offering them spiked drinks after pretending he had won money.

He was first convicted in 2009 of 19 sexual offences against 12 women between October 2006 and February 2008, and was given an indefinite sentence for public protection with a minimum term of eight years. In 2019, after more victims came forward about crimes he admitted to that took place between 2000 and 2008, Worboys was sentenced to life imprisonment with a minimum term of six years.

Carrie Johnson encountered Worboys in 2007 when she was a 19-year-old university student waiting for a night bus in Chelsea. He offered to drive her home for £5 in his black cab, then offered her a glass of champagne in the taxi, saying he had won a lot of money at a casino. Johnson poured the champagne onto the taxi floor to avoid drinking it.

Worboys stopped near Putney Common, exited the vehicle, returned with a bottle of vodka, and insisted that Johnson take a shot. He dropped her off at her mother's house after she told him her mother was waiting for her and gave her his phone number. After arriving home, Johnson passed out fully clothed in her bathroom bathtub.

Johnson later identified Worboys in a police lineup and provided the phone number he had given her to the police. Publicity around her experience led to further victims coming forward, and she said she had been contacted by more women who believed they had been assaulted by Worboys.

Speaking on Good Morning Britain, Johnson said his crimes spanned from 2000 up to his 2009 conviction and that there could be "up to 1,000, if not more than that" victims. She said she would urge women who think they may have been drugged by Worboys to come forward if they can.
