The airport called police Wednesday but it turned out to be a prank for a television show called "Balls of Steel," Sweden's TT news agency reported..
"It was a stupid prank that scared the airport staff but no law has been broken," said police spokeswoman Yvonne Lindholm.
The "Balls of Steel" program became notorious last year when a reporter sprayed water into the face of Swedish Prime Minister Fredrik Reinfeldt as part of a spoof interview.
