The man locked himself in a bathroom after yelling at around 11 a.m. that he had a bomb. Witnesses told Dutch state broadcaster NOS that he made the threat after refusing to pay for a meal at an airport restaurant, Associated Press reported.
Two terminals of the airport were evacuated and did not re-open until 4:30 p.m., DutchNews reported.
The man did not have identity documents with him and was difficult to communicate with, police said. It was determined that the man was Russian on Tuesday. It remained unclear how the man had entered the airport without identification papers.
