Seven members of the Cameroon Olympic team have disappeared during London 2012, according to the country's Ministry of Sports and Physical Education.
The seven – five boxers, a swimmer and a footballer – are suspected of having left to stay in Europe for economic reasons.
The team's head, David Ojong, said: "What began as rumour has finally turned out to be true. Seven Cameroonian athletes who participated at the 2012 London Olympic Games have disappeared from the Olympic Village."
Ojong said a reserve goalkeeper for the women's football team, Drusille Ngako, was the first to disappear.
