The Bill - Season 5 Episode 9 Duty Elsewhere

P.C. Haynes volunteers for ""duty elsewhere"", undercover as a driver for Neville Tubbs, leader of a Yardie gang in South London. A man has just been murdered and mutilated, and Rita, a girl from Tubbs' club tells Haynes she witnessed the killing. Gaining Tubbs' trust, Haynes is asked to transport a package to a meeting across town. He is stopped by two police officers, but manages to get away after telling them he's in the Job. Haynes delivers the package, but is recognised as a cop by a Brixton Yardie. The police raid the place before Haynes is hurt or killed, but he is horrified to discover the package he carried contains the murder victim's hands.
