Just before six thirty on Tuesday evening, SOS was alerted to a cardiac arrest in Halmstad.
The ambulance went to the apartment and then found the woman dead.
As the cause of death is unclear, the police have now started a preliminary investigation into murder.
The location network is cordoned off and must be investigated.
- Technicians will go out and begin a technical investigation.
We'll see if they find anything, otherwise it may take some time until a forensic examination is done, says police spokesperson Peter Adlersson.
The persons who have been deprived of their liberty must be questioned about the incident.
The police also continue to knock on doors.
