According to the police, the three are not unfamiliar with each other.

The abused man, who is in his 20s, and the affected woman, who is in her late teens, were taken by ambulance to hospital, according to the police, who initially initiated a preliminary investigation into aggravated assault.

The crime classification was then changed to attempted murder

- The reason for this is the actual choice of shelter, but this may change, says Johnny Gustavsson, spokesman for the police.

At lunchtime on Monday, a person in Norrköping was arrested on suspicion of the crime.

- When we arrived at the scene, the suspected perpetrator was not left.

After extensive reconnaissance work, we managed to find information about where the person was and he was arrested in Norrköping, says Johnny Gustavsson.

What can you say about the shelter used?

- It will be about a blush of a blunt nature, says Johnny Gustavsson.

The injury situation for the victims is unclear at the time of writing.
