This time its the Congolese....
"Four members of the Democratic Republic of Congo's Olympic delegation have gone missing in London, reports say.
Cedric Mandembo, who competed in judo, and coaches with the athletics, boxing and judo teams have not been seen since the closing ceremony on Sunday.
The DR Congo - represented in London by four athletes - failed to win a single medal. The delegation is due to fly back home later this week.
More than a week ago, five Cameroonian boxers deserted their Olympic squad.
The boxers told the BBC they wanted to stay in the UK to develop their careers."
