However, smart-thinking cops have found other innovative ways to tackle the problem. In 2012, Met Police officers used a borrowed No. 2 London bus to sneak up on a gang of street gamblers on Westminster Bridge. Normally, the lookouts alert the street gamblers well in advance but, on this occasion, they hadn’t anticipated the 30-plus officers who jumped out on them as the bus came alongside. More than 25 gamblers were detained and 12 were charged with gaming offences.
