The aircraft crew appealed for help when an aircraft was about to land at Arlanda on Saturday, the police write on their website.

The staff alerted that a traveler was "unruly" - which roughly means difficult to handle.

After the plane landed, the police checked the passenger, who is a man in his 20s. 

The man is said to have filmed the crew on board, which is not a crime under Swedish law. However, it is reported that it is a crime under Swiss law and therefore the airline will file a police report there instead.
