A Pakistan International Airlines jet had to land in Stockholm after officials were tipped off that someone on board had explosives and was preparing to sabotage that aircraft. The plane was headed from Toronto to Karachi before the unplanned stop in Sweden, and its 273 passengers were evacuated as a SWAT team detained the suspect, a 30-year-old Canadian citizen of Pakistani origin. He wasn’t on no-fly lists, and the tip was came from a woman in Canada. Police found no explosives on the man and a bomb squad is searching the plane. The man is still being questioned.
