A 45-year-old man has been arrested after he allegedly disrupted a Malaysian Airlines flight from Sydney to Kuala Lumpur, which was forced to turn around mid-flight and land back in Sydney International Airport on Monday.

“The man is expected to be charged later tonight,” according to a spokesman for the Australian Federal Police. No details of the charges or incident were given.

Police said all passengers were evacuated and there was “no impending threat to the community.”

“An emergency response plan was enacted, and an evacuation was initiated once it was deemed safe for passengers and crew,” police said.

According to several posts on the social media platform X, previously known as Twitter, a passenger believed to be on the plane said a man “started threatening staff and passengers.”

“Malaysia Airlines flight MH122 on 14 August 2023 returned to Sydney International Airport due to a disruptive passenger on board. In the interest of safety, the commander of the flight made a decision to return to Sydney,” the airline said.

“Currently there are no international flight cancellations,” the airport said.
