At 16 o'clock on Tuesday afternoon, the alarm came in to the police.
It was a private person who had found an object outdoors and the police do not want to go into what the object is at the moment.
It is not adjacent to any building or vehicle.
- Right now we do not see any threatening situation or that it is directed at any specific person or business, says Rickard Lundqvist, the police's press spokesperson.
Police have now cordoned off a large area around Citadelllvägen, north of the outer moat, and are waiting for specialists from the national bomb shelter.
