Malaysia Airlines flight MH122 left Sydney Airport at 1.40pm and landed back on the runway at 3.47pm on Monday after it turned around mid-air while over regional NSW, Flight Aware revealed.
The plane remains on the tarmac and is blocking one of Sydney’s major runways, with emergency services positioned nearby.
Passengers on board the flight have taken to social media to share details of the emergency, claiming an unruly male passenger was threatening staff and travellers.
7NEWS understands a threat was made on board on Monday afternoon, forcing the plane to turn around.
The man allegedly at the centre of the incident bought a one-way ticket and had no luggage.
However, a passenger has since told 7NEWS the man is now telling the flight crew it was all a joke.
There are believed to have been over 200 passengers on board the flight, including children.
Some delays are expected at the airport on Monday night.
In an update, Sydney Airport said it was “supporting emergency agencies in the management of an incident at the airport”.
“The airport is operational with flights arriving and departing,” it said.
“Passengers are encouraged to check directly with their airline regarding the status of their flight.”
