The International Cricket Council has launched its own investigation into the leaking of anti-corruption information to the British media.
In the last week match-fixing testimony from two New Zealand cricketers, Lou Vincent and Brendon McCullum, has been leaked to the media.
ICC chief executive Dave Richardson says the leaks completely undermine any trust or confidence players may have in cricket's anti-corruption systems.
Richardson says they've started an investigation through their ethics officer, but at this stage the police aren't involved.
He says it is too early to say that the leak came from the anti-corruption unit.
Richardson says they want to emphasise that McCullum is not under investigation in this matter.
