The incident occurred during the 10.5-hour journey aboard an Airbus A380-800. The crew member, who was scheduled to serve meals, vanished shortly after takeoff, prompting concern among colleagues.
A search of the double-decker aircraft ended in shock when he was found completely nude, dancing erratically inside a Club World toilet, The Sun reported.
Crew members quickly removed the man from the lavatory and secured him in a premium seat for the remainder of the flight, The Straits Times reported. He was restrained and kept under supervision while the rest of the team scrambled to manage service for the 470 passengers and crew on board, reportedly without taking any breaks.
Authorities and medical personnel met the plane when it landed at Heathrow Airport around 11 a.m. on May 25. The crew member was taken off the aircraft in a wheelchair and has since been suspended.
