Japanese authorities say they're trying to identify a body found inside one of the landing gear compartments on a Delta Airlines flight that arrived in Tokyo from New York.
Police at the Narita International Airport say the body of the apparent stowaway, identified only as that of a male with dark skin, was clad only in a long-sleeved, plaid shirt and jeans.
A mechanic found the body lying inside the landing gear compartment of the Boeing 777-200 during maintenance after Delta Flight 59 from New York landed at Narita on Sunday night.
Police say the body had no visible injuries except signs of frostbite, and the man might have died of hypothermia during the flight.
The temperature in that part of the plane falls to about minus 58 degrees during flight.
Police are investigating the case both as an accident and a possible crime.
