Simon and Chris are in High Wycombe to help clamp down on smash and grabs from cars. They aren’t in time to nab them on site, so they head off and help to box it in with a bit of help from Charlie and Lloydy. Not surprisingly, the thefts (of portable sat navs) are funding a drug habit. Chris and Simon, in Milton Keynes respond to a 999 call about blokes hanging around a car suspiciously. Simon recognises them, and Chris spots their ‘conveniently found’ screwdrivers. Guess what they’re doing, then? Even though the car they’re hanging around is abandoned, it’s still a bit on the suspicious – and one of them really, really doesn’t want to be arrested without realising that it’s all part of the Street Caution process. His behaviour leads to a full arrest, and Chris nearly has his arm bitten off by the car door! Rosie and Daz are in Reading and come across a madly speeding transit which they turn and head after.
