S7·E4 Closing Ranks

There is an out break of handbag snatches in the area, the police know who the perpetrators are but can't prove anything. Phil decides to take matters into his own hands when his Gran is the next victim. To ensure a conviction he plants her purse on the suspect, and asks Nick to go along with it, he does, but in court the suspect's solicitor finds holes in the evidence and Blaketon realises what's happened. The case is dropped. Blaketon is angry and threatens to report Phil and Nick for the incident but informs them the next day, that just this once he would let the matter drop. Blaketon then turns to Alf for help with the case, and they set up a successful identity parade, which provides enough evidence to make the charges stand up in court. Meanwhile Jo is having problems with her mother disapproving of Nick and Claude is told there's more to a stuffed ram than meets the eye!
