The crew on the Alaska Airlines Flight 2059 then reported the incident to air traffic control.
In audio recorded by LiveATC.net, the pilot said to Seattle-area air traffic controllers: "We’ve got the guy that tried to shut the engines down out of the cockpit, and he doesn’t sound like he’s causing any issues in the back right now.
"I think he’s subdued. Other than that, we want law enforcement as soon as we get on the ground and are parked.”

The flight, operated by Horizon Air, was scheduled to take off at 5.25pm, and arrive in San Francisco at 7.30pm.
But upon Emerson's alleged attempt at crashing the plane, the flight was diverted to Portland International Airport.
It then took off from Portland at 7.18pm in a bid to reach its final destination of San Francisco.
Alaska Airlines have issued a statement in the wake of the scary ordeal.
