The Bill - Season 16 Episode 44 Beyond Conviction

Klein and Hagen are called to a stabbing at a shopping centre, where a foreign aid worker has been attacked and left for dead. Initially, suspicion falls on a local youth, Wayne Stevens, who has previous for similar offences and was seen running away from the scene. However, when another witness claims she heard the victim shouting something before she was attacked, the pair find themselves on the trail of a Rwandan war criminal, Colonel Augustus Ngeze, who is wanted for mass genocide and rape by the UN. Klein's personal views begin to cloud his judgement when they fail to obtain any evidence to prove Ngeze's identity, so he sets up a chance meeting with a Rwandan national in an attempt to identify him.
