A non-stop Qantas flight from Perth to London was forced to turn back just two hours into its 17-hour journey on Saturday night due to a disruptive male passenger.
Flight QF9, which took off from Perth at 7.03pm, returned to the West Australian capital at 10.32pm London time.
The passenger was removed from the plane by Australian Federal Police.
The Flightradar24 app showed the plane returning to Perth west of Shark Bay.
One passenger said the man became 'agitated' and 'hyper-aggressive like a cornered animal' having returned to his seat after walking towards the bathroom.
According to PerthNow, the passenger said the man stood up and was 'shouting and pointing in an extremely aggressive manner'.
He said: 'Whatever happened next he was suddenly standing up and shouting and pointing in an extremely aggressive manner.
'I wasn't sure what he was saying. Passengers leapt in to control him - he was eventually marched down the back of the plane.
'He was by this time highly, highly wound up.'
The passengers praised staff for keeping everyone calm during the ordeal.
A Qantas spokesman said: 'We take a zero tolerance approach to disruptive behaviour on board.
'The safety of our crew and customers is our number one priority.'
The airline said customers were given overnight accommodation, with the QF9 flight due to leave Perth again on Sunday.
The service between Perth and London runs daily and is the first direct flight from Australia to the UK and was launched by Qantas in March.
The 9,000 mile journey is 24 per cent further than the UK's previous longest route between Heathrow and Jakarta - operated by Garuda Indonesia.
