WASHINGTON - A stowaway on a flight from Ethiopia was being detained in Washington and will be sent back, The Washington Post reported on Sunday.

Baggage handlers discovered the man, described as in his late 30s, in the luggage compartment of an Ethiopian Airways Boeing 767 that landed at Dulles International Airport on Saturday, the newspaper said.

The stowaway was dehydrated and exhausted but a Customs and Border Protection spokesman said he did not appear to present a threat, the Post reported.

Customs spokesman Steve Sapp told the newspaper the man, who was not identified, would face an administrative charge and would be sent back on an Ethiopian Airways plane.

A US Customs official did not immediately return a call seeking comment. -Reuters
