FIFA has refused to comment on whether or not an investigation is underway into allegations that Cameroon have been involved in match-fixing at the current World Cup.
The African nation’s football federation announced on Tuesday that it was investigating claims of "fraud" that occured during their Group A games, in particular the 4-0 defeat to Croatia in Manaus on Wednesday June 18.
A convicted match-fixer, Wilson Raj Perumal, is said to have accurately predicted the score of this defeat and that a Cameroon player would be sent-off in the first half – midfielder Alex Song was red-carded just before half-time.
But FIFA spokesperson Delia Fischer told the media: "We do not provide any comment as to whether or not an investigation is underway with regards to any manipulation of matches.
"The FIFA disciplinary code and code of ethics both say that only after a decision has been taken by the FIFA disciplinary commission or the ethics committee, and all parties concerned notified first, would FIFA be in a position to communicate that decision publically.
"Generally speaking, the integrity of the game is FIFA’s top priority and we take allegations of match-fixing very seriously.
"FIFA continues to work closely with law enforcement agencies on a national, regional and global level to tackle match manipulation."
The allegations levelled at Cameroon originated in a Facebook conversation between Perumal and German journalist Rafael Buschmann of magazine Der Spiegel.
