In a Daily Mail article from 2008, award winning journalist Eileen Fairweather reported on the links she discovered between child sexual abuse in Islington (a borough in central London) care homes and the horrific physical/sexual abuse and murder of children in the Haut de la Garenne children's home in Jersey (it is believed that BBC paedophile/necrophile extraordinaire Jimmy Savile procured children from Haut de la Garenne to be raped by former Prime Minister Edward Heath). She tells of how she was approached by a police officer and asked to act as an intermediary in passing on information to police abuse specialists in London because his superiors had barred him from doing so. The detective told her that many members of the ring were wealthy and powerful and had friends in the upper echelons of the police, so (and this seems to be the rule rather than the exception when it comes to police investigations into organised child rape gangs) investigations were shut down and the child rapists protected.
