‘On WhatsApp you send a voice message. They talk constantly about building up the round, build up the round, and that just means they come into an area, infiltrate the area and over two to three days, build up a customer database. They go down to [town] High Street at 11 am, sit outside the tunnels. You’ll see them going to score drugs. You’ve only got to approach one of them, “Hello, mate, y’alright, where you getting your gear, blah, blah. What's your name? I sell a bit of gear. What's your number? What's your mate's name? How many mates you got who take kit?” In one conversation you’ve got six names and numbers of people in town that are addicts. In two or three days you can build up a round. You’ve only got to give them a couple of free samples that they know your gear is good and they’ll spread, “Oh, there's a new fellow knocking about. He's knocking out some gear. His name's so-and-so.”’ (Police 02)

‘She’ll get there, meet the boys who take the drugs from her and she's catching that cab straight back. Then the boys they will go into the park or field, it's like a nine bar of each so it's all bagged up in G packs, you’ve got two G packs and then you would have 20 packs of stuff, all in 20s.
