Up to 1,000 children could have been abused in Britain's biggest ever child abuse scandal, an investigation has revealed. Hundreds of children, some as young as 11, are estimated to have been drugged, beaten and raped over a 40-year period in the town of Telford. Lucy Allan, the Conservative MP for Telford, has called for an inquiry into child sexual exploitation. The investigation claims that allegations dating back to the 1980s were mishandled by authorities in Telford, who repeatedly failed to punish a network of abusers. Victims claimed that similar abuse, which has been linked to three murders and two other deaths, has continued in the area. The newspaper's probe alleges that social workers were aware of the abuse in the 1990s, but that it took police a decade to launch Operation Chalice, an inquiry into child prostitution in the Telford area in which seven men were jailed. It is also claimed that abused and trafficked children were considered prostitutes" by council staff, that authorities did not keep details of abusers from Asian communities for fear of being accused of "racism" and that police failed to investigate one recent case five times until an MP intervened. The estimate of 1,000 potential victims was made with the help of Professor Liz Kelly, from the Child and Woman Abuse Studies Unit at London Metropolitan University. Twelve victims spoke to the newspaper and accused more than 70 abusers. Two other investigations were launched alongside Operation Chalice after two victims named dozens more abusers, yet victims have claimed that they were put off helping inquiries.
