The football federation of the African nation have confirmed that they are investigating alleged corruption claims after a German report alleged Wilson Raj Perumal involvement
Cameroon suffered three Group A defeats, to Brazil, Mexico and Croatia, as they scored once and conceded nine times to finish bottom of the table.
"Recent allegations of fraud around Cameroon 2014 Fifa World Cup three preliminary games, especially Cameroon vs. Croatia, as well of the "existence of seven bad apples [in our national team]" do not reflect the values and principles promoted by our administration, in line with FIFA Code of Conduct and the ethics of our nation," Owona said in a statement.
In the 4-0 defeat by Croatia, Alex Song was sent off while team-mates Benoit Assou-Ekotto and Benjamin Moukandjo extraordinarily clashed with each other.
The statement added: "We wish to inform the general public that, though not yet contacted by Fifa in regards to this affair, our administration has already instructed its Ethics Committee, to further investigate these accusations.
"We are strongly committed to employ all means necessary to resolve this disruptive matter in the shortest delays."
The investigation comes after a report in Germany alleged that Singaporean match-fixer Wilson Raj Perumal had correctly predicted the outcome of the Cameroon match against Croatia.
Perumal had claimed in a private Facebook message that Cameroon would lose the match 4-0 and have a player sent off. He had also alleged that there were 'seven bad apples' in the team.
