(CNN) -- Authorities arrested a passenger after a plane made an emergency landing in Sweden on Saturday morning, police said.
The plane -- which had 273 people onboard and was flying from Canada to Pakistan -- landed after a caller told authorities that a passenger had explosives with him.
All passengers were later evacuated from the plane, Stockholm Police spokesman Kjell Lindgren said.
The man in custody is suspected of "preparation of aviation sabotage," Lindgren said, adding that no explosives had been found yet.
"Right now we are still searching through the plane and the baggage, but we have found no expolsives on the man," he said.
He said police still are determining what exactly was said during the call that forced the plane to land. "Our priority is to find out what happened on that plane," Lindgren said.
The man was arrested in a "very nondramatic fashion" as passengers filed off the plane, he added. While the man was carrying a passport, police are still investigating his identity.
Pakistan International Airlines Flight 782 was heading from Toronto, Canada, to Karachi, Pakistan, when it landed because of "security reasons," said Sultan Hassan, an airline spokesman.
