A former Pakistan Test cricketer alleged that a national player had hidden a mobile phone inside the right earpiece of his helmet while waiting to bat during an international match.
Under ICC's regulations, players are not allowed to use cell phones on the ground during international matches, a move designed to prevent communication between match-fixers and players during matches.
The anonymous player has passed on the information to the International Cricket Council's Anti-Corruption and Security Unit.
"My reaction was one of disbelief," said the former Test player said.
"I had reason to suspect things were going on in international cricket, and you never had total confidence in certain games because of the rumours about match fixing and spot fixing. But when I was told about this player with the mobile inside his helmet, I was flabbergasted," he was quoted as saying in the Daily Telegraph.
The revelation comes a week after English tabloid News of the World broke the news of three Pakistan players' -- skipper Salman Butt and pace bowlers Mohammad Asif and Mohammad Aamer -- involvement in spot fixing in the Lord's Test.
The accused have been handed out temporary suspension by the ICC.
