The jetliner was on its way from Canada to Pakistan with 273 passengers on board. It made a unschduled landing at Stockholm's Arlanda airport after police were alerted by a phone call by an anonymous woman that a man on the plane may have an explosive device with himself.

The plane was evacuated while other passengers except the suspect have been taken care of at the airport, according to Stockholm district police spokesman Janne Hedlund.

Police searched the man and his baggage, but found no explosives, he added.

"He is not currently suspected more than on the information the anonymous woman left," said Janne Hedlund.

The plane, a Boeing 777, was on its way from Toronto to Karachi, Pakistan. Pakistan International Airways has confirmed that one of its plane has landed in Stockholm due to security reasons.
