Zimbabwean authorities Saturday released a US cargo plane that landed in Harare with an unidentified body, after an autopsy revealed the man had died of asphyxiation.
"Police, other security services, foreign affairs and immigration officials have cleared the crew which has since left for South Africa with the body and South African rand," a police statement said.
The plane was transporting a consignment for the South African Reserve Bank (SARB).
The MD-11 aircraft of Florida-based Western Global Airlines left Munich on February 13 en route to Durban, South Africa. It landed for refueling in Harare on February 14.
The six crew members were arrested after the male body, believed to belong to a stowaway, was discovered. The crew were unable to produce documents to account for his presence.
But the plane was released after an autopsy revealed that the man died because of asphyxiation, police spokesman Charity Charamba told dpa.
Police sources said last week that the plane had large amounts of South African rand on board.
