When we arrive, we understand that there has been some form of partying, with several people on site. One or more people have attacked a person, said police spokesperson Daniel Wikdahl during the night.
The man received care from ambulance paramedics but died, according to the police.
Three men were arrested after the incident.
One was arrested on site, the other had run away but was found with the help of a dog. In connection with the arrest, we used stun guns.
All three arrested men have been detained, the police announced on their website.
Many of those who followed the police had been noticeably intoxicated.
It will take some time before the circumstances of what happened and why become clear, said Daniel Wikdahl.
The apartment is cordoned off for a technical investigation.
