Cameroon's football federation, Fecafoot, has confirmed that an investigation has been launched following claims of match-fixing in their games at the World Cup.
A statement revealed that their ethics committee will look into the games against Mexico, Croatia and Brazil, but it has been reported that the investigation will focus on the 4-0 defeat to Croatia in Manaus.
The initial allegations against Cameroon came from convicted fraudster Wilson Raj Perumal, who had correctly predicted the result and that a Cameroonian player would be sent off in a discussion with German magazine Der Spiegel. Alex Song was shown a red card for elbowing Mario Mandzukic in an incident off the ball before half time.
"Recent allegations of fraud around Cameroon's three 2014 World Cup games, especially Cameroon vs. Croatia, as well as the existence of 'seven bad apples' [in our national team] do not reflect the values and principles promoted by our administration," a Fecafoot statement confirmed.
"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."
Cameroon also suffered defeats to Mexico and Brazil in their Group A campaign.
