Swedish police say a man detained after a tip-off that he was carrying explosives on a Pakistan International Airlines jet has been released. Stockholm police spokesman Kjell Lindgren says a prosecutor decided to let the man go after questioning. The plane was bound from Toronto to Karachi with 273 people aboard, but it was diverted to Stockholm after Canadian authorities received a tip that the man was carrying explosives.

Swedish police evacuated 273 people from a Pakistan International Airlines jet diverted to Stockholm due to a bomb alert Saturday and detained a passenger on suspicion of preparing aircraft sabotage, officials said. However, no explosives were found on the man or on the Boeing 777, and all passengers — except the suspect — were allowed back on the plane nine hours later. It took off for Manchester, England, from where the passengers would continue their journey to Karachi, said Jan Lindqvist, a spokesman for airport operator Swedavia. The Royal Canadian Mounted Police said it was investigating whether the incident was a "terrorism hoax." The plane was traveling from Toronto to Karachi when the pilot asked to land after Canadian authorities received a tip that a passenger was carrying explosives.
