Presented by actor and presenter Will Mellor, Cops Gone Bad covers seven new cases to expose murderers, fraudsters, swindlers, sexual predators and drug dealers within the police force. Will returns with his team of experts: retired Detective Chief Inspector Howard Groves and forensic psychologist Serena Simmons. Also joining them is former Detective Chief Superintendent Sue Hill, who has been investigating serious crime for over 30 years. The new series launches with the deplorable story of David Carrick, the serial rapist who used his position of authority at the Met Police to commit unthinkable acts.
