Serial taxi rapist may have attacked over 100 women

At the time, detectives linked him to at least 85 crimes. But Scotland Yard said yesterday that a number of women had come forward since he had been placed behind bars, and that his alleged victims now number more than 100.

About 19 women have made allegations against Worboys since his conviction, police said. It is thought that there may be still more victims who have not come forward.

Not all the women claimed the former stripper and adult film star had raped them, but all accused him of sexually motivated offences.

The attacks are believed to have been carried out over a period of about five years, between 2002 and 2007.

A Metropolitan Police spokesman said: "There is a high possibility there are more victims out there.

"The difficulty is that a large number of the women do not know whether they were raped or not. The only person who knows is Worboys himself.

"We hope he might consider telling us in the future what went on."

In March 2009 Worboys was found guilty at Croydon Crown Court in south London of assaulting 12 women during an 18-month reign of terror in the capital. He was jailed indefinitely following his conviction.

Many of his victims were young women who had been drinking in night spots in the West End and Chelsea.

Worboys offered them Champagne spiked with powerful sedatives to celebrate a fictional lottery win, which he backed up by carrying a carrier bag stuffed full of cash. The drugs left the women insensible and unable to protect themselves as Worboys pounced on them in the back of the vehicle.

A helpline has continued to receive calls from women who say they were targeted by Worboys and police have been speaking to them during the past 18 months.

Worboys was told that he must serve a minimum of eight years in prison for the attacks and would not be released until parole officials were convinced he did not pose a threat to women.
