A passenger was arrested at an Australian airport on Thursday after exiting a stationary commercial plane through an emergency exit, walking along a wing and then climbing down a jet engine onto the tarmac, officials said.

Jetstar flight JQ507 arrived at Melbourne Airport from Sydney and was parked at a gate in the terminal when the man exited the plane through the right exit, officials said.

When the exit was opened, a slide automatically extended from the rear of the wing on the fuselage to the ground, a Jetstar statement said. But the man instead walked along the wing and climbed down one of the Airbus A320’s two engines, an official said.

Passenger Audrey Varghese said passengers were screaming and shouting when the man displayed “erratic” behavior shortly before the hatch was opened.

“The man was exhibiting some pretty strange behaviour,” Varghese told Melbourne Radio 3AW.

“As soon as the plane came to a stop, he immediately stood up and rushed to the emergency exit row,” Varghese added.

Australian Federal Police officers were alerted by Jetstar employees and arrested the man for “alleged aggressive behaviour and breach of aircraft safety protocols”, a police statement said.

He was examined by paramedics and taken to a hospital where he will remain for further examination, the police statement said.

Police are continuing to investigate and charges are likely to be filed at a later date, they said.

Melbourne Airport said the man was detained by flight crew and ground staff before police arrested him.

“Melbourne Airport is proud of the exceptional response of ground staff, which resulted in no immediate danger to other passengers or airport staff,” the airport said in a statement.
