A body was discovered in the landing gear compartment of a United Airlines plane after it landed in Hawaii on Christmas Eve.

Flight 202 departed from Chicago’s O’Hare airport on Tuesday morning and arrived at Maui’s Kahului airport in the afternoon.

United Airlines said it remained unclear how or when the person accessed the landing gear, which is only accessible from the outside of the Boeing 787-10 aircraft.

The company is collaborating with law enforcement authorities on the investigation.

The deceased person’s identity has not been released.

The police department told Hawaii News Now that it is investigating the deceased individual found on the flight. No further details are available at this time.

The BBC has reached out to the Maui Police Department for additional comments.
