A highly-organised paedophile ring involving Victorian police and former politicians had been operating in the state since the 1970s, anti-child abuse groups claimed today. Dr Reina Michaelson of The Child Sexual Abuse Prevention Program (CSAPP) and Bravehearts founder Hetty Johnston today said they had been told by child sex abuse victims that former Victorian elected politicians and police members were involved in child pornography and prostitution. Dr Michaelson said she was working with child sex abuse victims who said they had witnessed significant police corruption and protection of paedophilia rings. The allegations come in response to a damning report released by Victoria's Ombudsman George Brouwer yesterday into Victoria Police's botched handling of four cases of child sex abuse. Ms Michaelson and Ms Johnston today called for the confidential Ombudsman's report to be made public and for a royal commission into child sexual abuse and corruption. When problems within Victoria Police are shown to have extended into the investigation of serious sex crimes against children, as has been revealed by the Ombudsman's investigation, it is time for the Victorian government to act," Dr Michaelson said.
