Omar Benguit has spent 23 years in prison for murder, but there's no CCTV or forensic evidence linking him to the crime. The main prosecution witness is a proven liar with a history of making false allegations. Panorama reveals how the police built their case around her, even though they had evidence that discredited her account. Reporter Bronagh Munro, who has been investigating the case for ten years, also talks to witnesses who say they were pressured to lie in court and finds information that strengthens Omar Benguit's alibi. The new evidence raises serious questions about the police's original investigation and suggests he may have been framed for murder. Dorset Police say the case has been dismissed twice by the Court of Appeal and that its investigation was thorough, detailed and very complex.
