Police were ordered to the address shortly before 6 p.m. and found a deceased woman there, which Göteborgs-Posten was the first to report.
– We cannot rule out crime and that is why we have started a preliminary investigation into murder, says Fredrik Flyberg, duty officer in the West region.
He adds that the man who was arrested is also in his 60s, but is withholding further information about the circumstances.
