A former South African national player has been charged with corruption involving match-fixing, ESPNcricinfo has learned.

The player, who has yet to be named, is understood to be the same "intermediary" who was the subject of a CSA press release in December, following attempts to influence results in South Africa's domestic competition, the Ram Slam T20 Challenge.

In their original statement, CSA said the intermediary had been charged under its anti-corruption code with "contriving to fix, or otherwise improperly influence aspects" of the 2014-15 domestic Twenty20 competition.

The person involved had also been charged with "failing, or refusing without compelling justification, to cooperate with an investigation carried out by an anti-corruption official."

South Africa's Prevention and Combating of Corrupt Activities Act Law was introduced in 2004 and included a so-called "Hansie clause" to tackle corruption in sporting events, such as those for which Hansie Cronje, South Africa's former captain, received a life ban from cricket in 2000.

ESPNcricinfo also understands that other players involved in the competition will face the lesser charge of failing to report an approach, a breach of the ICC anti-corruption code that carries a ban of up to five years if found guilty.

"Our attitude to corruption will always be one of zero tolerance and we are confident that we have the necessary structures in place to effectively deal with any corrupt activity," said Haroon Lorgat, the CSA chief executive, in December.

"We will relentlessly pursue under our code and the law of the land any persons we believe to be involved in corrupting the game and, with assistance from the police, we will also seek criminal prosecution."
