The former nanny to Fred and Rose West has told of her ordeal at the hands of two of Britain's worst serial killers. Caroline Roberts was just 17 when, in 1972, she went to work at the Wests' infamous 25 Cromwell Street home in Gloucester, where nine bodies were discovered more than 20 years later. What she witnessed and went through at their hands was to serve as a chilling prelude to the series of at least 12 murders the couple would go on to commit. Ms Roberts - called Caroline Owens in 1972 - was abducted and raped by the Wests but managed to escape.
