A Pakistan International Airlines Boeing 777 with about 250 passengers flying from Canada to Pakistan was evacuated after being diverted to Sweden due to a bomb threat, and police detained one man.
A woman called Canadian police after the plane had taken off from Canada, saying a man on board had explosives with him, Stockholm district police spokesman Janne Hedlund said.
No explosives were found on the man, who was detained while passengers were being evacuated from the plane, Hedlund said. His baggage and the plane were being searched, he said.
The plane was diverted to Arlanda, the Swedish capital's main airport, after Canadian police informed the pilot of the threat while the plane was in Swedish airspace.
Passengers walked slowly in line to waiting buses. Armed policemen were seen taking up position near the plane, although fog made it difficult to see clearly what was happening.
Police were still investigating whether the man had explosives.
