Passenger allegedly opens emergency exit door on taxiing plane, deploys slide at Atlanta airport: police

The incident triggered a security scare at Hartsfield-Jackson Atlanta International Airport and prompted the Amsterdam-bound aircraft to return to the gate, where officers boarded the plane. 

The Atlanta Police Department said the passenger, 32-year-old Johannes Van Heertum, had called 911 from inside the aircraft, claiming he saw another traveler with a weapon. Investigators said Van Heertum seemed to have panicked and acted out, forcing the aircraft to return to its ramp.

He was then transported to the Clayton County Jail without incident, and APD's Homeland Security Unit was notified.

KLM Airlines did not immediately respond to a request for comment from Fox News Digital.
