A plane passenger has been arrested after an emergency door was opened as the jet was about to take off.
It triggered the evacuation slide moments on the runway.
The arrested man alleges that someone was about to attack him.
The horror moment took place moments before the Thai Airways International flight was about to take off at around 9.05pm yesterday (7 Feb).

The flight was departing Chiang Mai in northern Thailand, bound for the country’s capital, Bangkok.
The unnamed 40-year-old man was nicked after the front emergency door was opened while the plane was taxiing on the runway.
The cabin crew managed to subdue the Canadian man with the help of another passenger.
The passengers on board had to return to the terminal to board another flight, which departed at 12.34am.
Airport workers had to cut the slide away from the plane and the runway was eventually reopened at around 10.50pm.
In the meantime, three outgoing planes and eight incoming flights were delayed as they had to circle the airport until the runway was cleared.
Two flights were diverted to other airports and 2,296 passengers on 13 planes were affected by the incident.
The Canadian man was placed under arrest and an investigation is ongoing.
