Zimbabwean police have arrested six crew members of a US cargo plane after a body was found on board, police said Monday, according to dpa. The body was believed to belong to a stowaway, said the South African Reserve Bank (SARB), for which the plane was carrying a "consignment." The MD-11 aircraft of Florida-based Western Global Airlines left Munich late Saturday en route to Durban, South Africa, said Florian Steuer, a spokesman for the German airport. It was not clear what the plane was transporting, but Zimbabwean police sources said it had large amounts of South African rand on board. The crew were arrested after a male body was discovered on the plane and the crew were unable to produce documents to account for its presence, according to Zimbabwean police and aviation officials. Police sources said the body was dripping with blood.
