A body was discovered in the landing gear of a plane belonging to Cameroon air transport company CAMAIRCO after it landed at Paris' Roissy-Charles de Gaulle Airport on Monday, an airline official said.
"The man, about 30 years old, probably sneaked into our plane to go to France before it took off from Douala airport. We don't know," CAMAIRCO's commercial director, Christian Perchat, told Reuters by telephone.
Security forces discovered the body in the landing gear after the plane landed at the Paris airport, he said. An investigation was under way.
