An Air Canada passenger opened an aircraft door and fell about 20 feet to the ground, Global News first reported.

An airline representative told Business Insider the incident involved a Boeing 777 at Toronto Pearson International Airport.

The spokesperson said the passenger “boarded the aircraft normally” but then opened a cabin door instead of going to their seat.

The representative added that the person sustained injuries from the fall and emergency services were called.

Data from Flightradar24, a flight-tracking site, shows Monday’s flight from Toronto to Dubai took off almost six hours late. It was scheduled to have 319 passengers on board.

An airline representative said: “We can confirm all of our approved boarding and cabin operating procedures were followed; we continue to review the incident.”

It’s the second time in less than a week that a passenger’s unusual behavior has delayed one of the airline’s flights.

On January 3, Air Canada diverted a flight after a 16-year-old passenger assaulted a family member, police said.

Police said other passengers and crew on the flight from Toronto to Calgary, Alberta, restrained the teen, who was arrested and taken to a hospital.

After being on the ground in Winnipeg, Manitoba, for about two hours, the flight landed in Calgary about three hours late.
