A man who was found dead last week by the E6 in Fjärås south of Kungsbacka came from southern Norway, reports Norwegian Fædrelandsvennen.
The Norwegian, who is suspected to have been murdered, was in his 40s, which Göteborgs-Posten had previously reported.
A 55-year-old Swedish man was arrested over the weekend, suspected of murder.
We have no motives and see no connection between the arrested man and the deceased, says police investigator Stina Frenning to GP.
