Passengers and crew members had to exceed a 17-year-old, who was on a plane with a rifle and ammunition in Australia.
This happened when the plane was preparing to fly from Avalon Airport, near Melbourne, before a flight bound to Sydney on Thursday afternoon, carrying about 160 people.
Police believe that the teenager came to the airport by breaking a security fence before climbing the front steps to the plane.
The footage published by the Australian Outlet 7news has shown that the suspect is restrained by a passenger while a member of Ground Crew and a pilot removed a utility belt containing tools that the suspect carries.
The pilot can also be seen kicking the rifle away from the teenager wearing a fluorescent jacket.
“How is this possible?” Someone on board may be heard to say to the frames.
Victoria's police said the 17-year-old, who is from the nearby Balarat region, was held in custody.
Chief Michael Reed told reporters that passengers have noticed that the teenager is wearing a gun while climbing the steps to the plane.
“The male was overcome by three of the passengers,” he said.
Soup Reed said the local force is in contact with the police to combat terrorism, but it is too early to establish a motive.
“Without a doubt, this would be a very terrifying incident for passengers,” he said, as he praised the “courage” of those who have prevailed for suspects.
Barry Clark, one of the passengers, told Australian public television operator ABC that the teenager seems to be dressed as an airport worker and “excited”.
He said, “All I could do was take the gun out of the road … and then put it into a detention and throw it to the ground until the police came.”
No one was injured during the incident, police said. Investigators deployed a car and two bags belonging to a suspect nearby.
Avalon Airport is served exclusively by Jetstar, a budget airline operated by Qantas.
In a statement to the US partner of BBC CBS News, the company said it was working with the authorities to investigate the incident.
“We know that this would be a very difficult situation,” a statement said. “We are sincerely grateful to the clients who have assisted our crew to safely manage the situation.”
Avalon airport CEO Ari Sus said the airport had opened again.
