Officers were waiting for the Emirates Airlines flight from Dubai when it landed in Stockholm Sunday.
Passengers told the TT news agency the suspect went berserk shortly after takeoff and tried to force his way into the cockpit while claiming he had a bomb. He was tackled by crew members and tied up for the remainder of the flight.
"There was no chance he would have been successful in trying to get into the cockpit," Kenneth Knuts of the border police at Arlanda told TT.
Stockholm police told Expressen the suspect was a Sri Lankan national.
