Police in Sweden said parts of the government's headquarters in Stockholm have been evacuated after employees discovered a suspicious-looking package.
Police spokesman Ulf Lindberg says government staff alerted police after discovering the incoming package.
He said on Thursday police also deemed the package suspicious and alerted bomb experts.
The building houses the offices of several ministers, including that of Prime Minister Fredrik Reinfeldt, who was not in the building at the time.
Lindberg says police have identified the package's sender. Police are preparing to remove the package and will allow workers back into the building once it leaves.
