Cameroon have launched an investigation after allegations of match-fixing were made against seven players at the World Cup.
FECAFOOT, the country's football federation, has instructed its ethics committee to investigate claims of ‘fraud’ in their Group A games, particularly the 4-0 defeat to Croatia in Manaus on Wednesday 18 June.
The allegations against Cameroon came from convicted match-fixer Wilson Raj Perumal, who accurately predicted the Croatia result and the fact a player would be sent off during a discussion with German magazine Der Spiegel.
Cameroon midfielder Alex Song was dismissed before half-time for elbowing Croatia's Mario Mandzukic and his 10-man side slumped to a heavy defeat.
A statement from FECAFOOT read: "Recent allegations of fraud around Cameroon's three 2014 World Cup games, especially Cameroon v Croatia, as well the existence of ‘seven bad apples (in our national team)’ do not reflect the values and principles promoted by our administration.
"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 with the shortest delay."
Cameroon lost all of their games in the group stages, suffering a 1-0 defeat against Mexico and a 4-1 thrashing by hosts Brazil.
