Police have arrested a man at Toronto's Pearson Airport after he allegedly breached a security gate and tried to board an airplane.
Video of the incident on YouTube shows a man holding a briefcase surrounded by officers, with one officer aiming a weapon at the man's chest.
The video shows Peel Regional Police repeatedly asking the man to drop the briefcase, then the sound of a bang went off.
The man screamed, shook and slumped forward to the ground where other officers handcuffed the man's arms behind his back.
There was no immediate word of any possible charges.
The man's name has not been released, nor have police indicated where he is from.
It is unclear what flight he was attempting to board, but the YouTube video, uploaded by user Vinay Saini, says the man was trying to "forcefully board" a Turkish Airlines flight.
