Chris and Mike are in Exeter in a marked Beemer and are called to have a word with a couple of youths lurking with a pushbike. It takes a bit longer than expected, but they finally spot a likely looking character – who spots them and nips off down an alleyway. Mike knows where the youth will emerge and they are soon behind them, even though he runs a red to try to get away.
