He screamed at and insulted airport cleaning staff and refused to calm down and behave himself when asked to by security officials.
He then demanded a police officer hand over his service weapon so that he could shoot himself with it.
The police officer refused and arrested the man – who was later taken to hospital in Graz on a doctor’s recommendation.
Police said that no one was injured and they are investigating what the man was doing at the airport and why he was so drunk.
