In January 2008, a 29-year-old insurance broker made a similar report to Essex police. In February 2008, Worboys raped a lawyer in his cab, who reported this to the police. These three reports convinced police that they were dealing with a serial rapist and they made a public appeal. A member of staff at a sexual assault referral unit remembered the 2007 case and Worboys was arrested at his house in Rotherhithe. Police found a "rape kit" in the boot of Worboys' Fiat Punto, containing champagne miniatures, plastic gloves, a torch, vibrators, condoms, sleeping tablets and an ashtray he used to crush drugs. In a safe in Worboys' garage police found hand-written notes outlining his planned explanations if he was questioned again following his 2007 arrest. These papers were not used in court because he claimed to have written them for his solicitor. Worboys' DNA was recovered from a semen stain in one woman's underwear, a wristband belonging to another woman was found in his house and a third victim's address was found in his notebook. Forensic evidence linked a vibrator found in his car to another victim. Worboys pleaded not guilty to all 23 counts brought against him. Fourteen women testified in court. Worboys claimed to have engaged in "banter" with the women "to get their attention", due to not getting "attention and cuddles" when growing up. He said that any sex was consensual. His defence counsel described Worboys as an "oddball", a "weird customer" and a "socially inadequate individual", but told the jury it did not mean Worboys was guilty, saying: "What have the prosecution got? They have got a lot of young women who had a very strange experience in the back of a taxi. It is not normal to be offered a drink by a taxi driver. The temptation for the jury is to say he is weird, he must have done it. Don’t fall into that trap". Worboys was convicted at Croydon Crown Court on 13 March 2009 of one count of rape, five sexual assaults, one attempted assault and 12 drugging charges, committed from July 2007 to February 2008. He was cleared of two counts of drugging. He was sent for a pre-sentencing report and a psychiatric report, and was sentenced on 21 April. He received an indeterminate sentence of imprisonment for public protection with the minimum custodial term set at eight years. Mr Justice Penry-Davey said he would not be released until the parole board decided he no longer presented a threat to women.
