John Wedger said he was forced into early retirement from the Metropolitan Police. The former detective constable has begun a civil claim against Scotland Yard seeking damages for psychiatric injury arising from work-related stress. Mr Wedger, 47, was involved in an investigation into a well known prostitute in 2004 who was suspected of using children. She was linked to organised crime but intelligence from multiple sources" suggested she also had connections within the local police. The prostitute would ply youngsters, including a 14-year-old girl, with drugs and alcohol and then pimp them out to men in budget hotels. During the course of the operation, Mr Wedger says he found that not only were the police aware the youngsters were being used for sex but he believed at least one officer was supplying the criminal gang with information about the investigation. After filing an intelligence report, he was brought in to see a senior officer at Scotland Yard headquarters. Mr Wedger said: "He told me in a firm and formal manner that I had 'dug too deep'. He then stated that if I mentioned a word of my findings outside of his office then he would make sure I was 'thrown to the wolves'. On his last day with the unit he was called in by the same officer. "He said, 'You must give your word that you will never look into child prostitution ever again.' The experience left me traumatised and paranoid."
