We go there, meet her and can shortly thereafter apprehend a identified perpetrator, says the police's press spokesperson Evelina Olsson.
The two individuals are already acquainted with each other. The police's understanding is that no other person is involved in the incident.
The woman has been taken to hospital by ambulance.
We have cordoned off the apartment where the crime is supposed to have taken place, and technicians will arrive at the scene during the evening. Then we are talking to neighbors and knocking on doors to see if anyone has information to provide, says Olsson.
The police have also cordoned off the outdoor area where the suspected perpetrator was apprehended, which is located near the residence.
The alarm about the incident came at 19:00 on Friday.
