New Zealand police say they evicted several "betting cheats" from Saturday's Cricket World Cup opener between New Zealand and Sri lanka as part of an international crackdown on corruption. The spectators were accused of "court-siding", the practice of relaying information from the ground to people overseas, taking advantage of broadcasting time delays to manipulate betting. "We know what to look for," World Cup policing Commander Sandy Manderson said without detailing how many people were caught. "We're aware that people are attempting to operate at venues and they will be detected, evicted and trespassed from all venues." Court siding is not illegal in New Zealand, but it is a breach of the terms and conditions of ICC Cricket World Cup tickets. It is different from match-fixing, which is the manipulation of sporting events to achieve a pre-determined outcome.
