A man threatened to bring down a Lufthansa flight from Germany to Serbia, according to the Associated Press.
Passengers said the man acted erratically since the beginning of the flight and began banging on the cockpit door demanding to be left inside.
Investigators say he threated to open a plane door during the flight.
The cabin crew and passengers were able to control the man until the plane landed and police came aboard.
The Associated Press reports that the majority of the passengers were unaware what was happening at the front of the plane.
