The International Cricket Council has served an injunction against a British newspaper in a bid to prevent further leaks into its anti-corruption investigation reaching the public.

The ICC plans to launch an investigation into how testimony from New Zealand players Brendon McCullum and Lou Vincent was leaked to the Daily Mail.

The newspaper published those details, outlining Vincent’s involvement in fixing across at least five countries and McCullum’s experience in being approached twice by the same player to fix games.

ICC president Alan Isaac told Radio New Zealand the organisation had taken steps to to prevent the newspaper releasing further information it holds.

He couldn’t outline the legal reasons for the move.

“We’re trying to stop it on the grounds that it’s not helpful,” he said.

New Zealander Isaac reiterated the ICC’s disappointment that confidential testimony was leaked, describing it as “totally unacceptable”.

A forensic investigation into the leaks will include inquiries at ICC member bodies, where respective anti-corruption staff received copies of the testimony reports.

“It was distributed in tightly controlled fashion and unfortunately somebody has let us down obviously,” he said.

“What we’re going to have to investigate is how widely those individual people may have distributed the report from there.”

Isaac couldn’t rule out the boards of various cricket nations seeing a copy of the reports.

New Zealand Cricket has said its chief executive David White never saw a copy.
