S5·E14 Cock-Up

P.C. Hollis is referee for a five-a-side football match between two schools organised by the Met. One of the players is Sgt. Cryer's son Danny, and Cryer breaks up a fight in the locker room when Danny accuses one of his team-mates of taking drugs. It turns out there is a big drug problem at Danny's school, Medway Comprehensive, and a local shopkeeper is found to have form for dealing. The shop is put under observation, and when two girls from Medway are seen leaving the shop, D.I. Burnside orders a raid. The girls are arrested and searched, but it turns out they were just buying fags, and they are also underage to consent to a search. No drugs are found in the shop, and the owner threatens to sue Burnside.
