The first alarm came at 18.41 from a parking lot near the Norrviken commuter train station in Sollentuna municipality.

- It is a person who has been abused by four perpetrators who are described as young people. They must have practiced punches and kicks and then deviated from places. I don't know what the reason is, says Per Fahlström at the police command center.

The second alarm came in just over an hour later.
