Airline staff took the man to a seat in the back of the plane and supervised him for the rest of the flight.

'It will be alleged the man was intoxicated at the time of the incident,' an AFP spokesman said.

When the plane touched down in Sydney, he was arrested and charged with an alleged breach of the Civil Aviation Act of threaten safety of aircraft.

Australian Federal Police (AFP) Inspector Dom Stephenson says passengers should feel safe and not have to endure reckless behaviour while flying.
