USE OF PROTOCOL PART 1

Use of Protocol Part 1-Episode 318 
Zain agrees to a stint with Sun Hill CID, with his first job being to wrap up the investigation into Joshua Armstrong. He and Terry begin an operation to nab local dealers to work their way up the food chain. Zain manipulates one of his old friends into revealing the location of Armstrong's drug-making factory. Meanwhile, Tony and Leela deal with a market trader selling counterfeit goods, but he responds to his arrest by making a false allegation of assault against Leela. Yvonne is suspended from duty following the death of Lee Thomas, which has a knock-on effect when Tony confronts a group of crackheads, seizing their rocks – and finds himself on the receiving end of a savage beating.
