Sapp says the stowaway was an Ethiopian man who was exhausted and dehydrated. He was taken to Reston Hospital Center and is now being held at a federal detention center.
Sapp says the man has been charged with being a stowaway and will be deported, but is not a security threat.
He says the flight departed from Addis Ababa and stopped in Rome before landing at Dulles shortly after 9 a.m. Saturday.
