This was the shocking moment a man was subdued by police at Dallas Fort Worth Airport on Thursday (February 13).

Footage shows the man arguing with police who had teasers at the ready when the altercation escalates forcing authorities to discharge their weapons - to little avail - and subsequently subdue him.

Shocked onlookers watched on as there was a continued struggle to keep the man properly detained.

The filmer explained: "I came in after the initial conflict with a gate agent, where he was asked to put out a cigarette.

"When I rolled up he was yelling at the guy in red and dumping water on his head.

"After watching and listening to him he was straight up on another planet.

"He was yelling at the gate agent dumping water on him mocking him.

"[He[ pushed a female agent and took a swing at her, they walked him down to where it was less crowded to calm him down, but he was just being crazy and causing a scene and started swinging so they dropped him!"
