Cameroon investigate kelong claims
In response to the Der Spiegel report, Cameroon's football federation (Fecafoot) said in a statement: "Recent allegations of fraud around Cameroon's 2014 Fifa World Cup three preliminary games, especially Cameroon v Croatia, as well of the 'existence of seven bad apples' do not reflect the values and principles promoted by our administration, in line with Fifa Code of Conduct and the ethics of our nation.
"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."
A report in UK's The Guardian newspaper on June 23 quoted Cameroon coach Volker Finke denying allegations of match-rigging after Cameroon's loss to Croatia.
He said: "I find it completely impossible that my players would give away the match. Don't worry about that at all."
