The alarm came in at 6:10 a.m. from a passerby who reported an object lying in a doorway on Nybrogatan.
Several police and emergency service units were dispatched and a large area around the street was cordoned off. The police also asked people in the nearest building to stay indoors and the national bomb disposal unit was called to the scene.
After the bomb squad examined the object, the police announced at 8 a.m. that it was deemed harmless and that the cordons would be reduced.
