S15·E13 Badlands

DS John Boulton is determined to catch a pair of brutal thieves, and he is certain that local crook Mick Glover is one of them. Ignoring protests from Uniform, who already have Glover under surveillance, Boulton leads a disasterous raid on Glover's flat, which puts PCs Quinnan and Garfield's informant Janie in grave danger. When Quinnan and Garfield find Janie's flat on the Jasmine Allen estate vandalised, Quinnan pursues the suspects, but finds himself seperated from Garfield, who can only watch in horror as his friend is beaten and stabbed by a gang of youths.
