Shortly before 10 p.m. on Monday, an alarm was raised that a woman and a man had been injured outdoors in a residential area in Västerås. The people were taken by ambulance to hospital, where the woman later died of her injuries.
The man reportedly escaped without life-threatening injuries.
It was a passerby who found them and called us, says police spokesperson Magnus Jansson Klarin.
According to the police, the people were injured with a sharp object and the incident is being classified as, among other things, murder. Later that night, the police stated that four people had been arrested for involvement in the incident.
The initial classification is murder, attempted murder and aiding and abetting murder for all of them, but this may change, says Joar Källman, regional command officer at the police.
During the night, the police did not want to release any more information about the people involved or the course of events.
Several police patrols have been in the area during the evening and night. The site has been cordoned off for technical examination and the police have also conducted interviews with witnesses.
The alarm came at 9:50 p.m.
