- One person has been taken to hospital and one person has been arrested, says Torbjörn Roos, duty officer at the police in the Bergslagen region to TT

The alarm came just before half past eight on Monday night. Both police and an ambulance were called there and the area is cordoned off while a technical investigation is carried out.

It is unclear how injured the person who was taken to hospital is. Officers on duty in the Bergslagen region could not confirm whether it had happened indoors or outdoors, but earlier in the evening, press spokesperson Christina Hallin was able to confirm to the radio that it had happened indoors.

Nor can the police at present determine the criminal classification of the incident.

- It is too early in the investigation, says Christina Hallin to P4 Dalarna.

She also tells the radio that the crime that took place is not a sexual crime.
