On Saturday, the police carried out a forensic examination in the house and now a forensic examination is awaiting to determine the cause of death.
"The reason for the classification is that we were told in the interrogation that there should have been an assault in this house earlier in the night of Saturday. We will now investigate whether the assault has anything to do with the death, it is too early to say at the moment, says Anna Westberg, police spokesperson.
She adds that the police do not see any connection to gang crime.
Next of kin have been notified.
