The circumstances surrounding the incident are currently unclear.
Police were alerted to the area shortly after 11pm on Saturday night after bangs had been heard by residents in the area.
On the spot, the police discovered two bullet holes, one in a door to a stairwell and one in a window pane.
- There are no plaintiffs, no suspects and no one has been injured in connection with the incident, says police spokeswoman Anna Göransson.
The reason why the police have initiated an investigation into attempted murder is for investigative technical reasons.
