One person is being arrested. On Wednesday, he reported himself to the police.

- He contacted us completely by himself and when we asked him to come to the station he did so, says Thomas Tellebro, criminal commissioner for serious crimes in Eskilstuna.

The man is suspected of serious weapons offense and grossly injurious to bodily harm. It is unclear what is behind the incident.

- We don't really know what happened right now and are working to find out why it turned out as it became, says Thomas Tellebro.

The man's injuries were reported to be minor.
