LONDON — Seven of Cameroon's Olympic competitors have disappeared from their official residence and may be attempting to seek asylum in Britain, the chief of the African nation's delegation was quoted as saying Tuesday.

The British news agency Press Association said David Ojong, the Team Cameroon chief, told his government that five boxers, a swimmer and a soccer player left the athletes village in Stratford, east London, over the weekend and have not returned. The state-run Cameroon Tribune newspaper published a similar report, also quoting Ojong.

A sports reporter in Cameroon said some athletes had hinted before departing for London that they might attempt to stay there.
