The police were called to the apartment at 8.30am on Saturday.
There, a woman in her 70s was found dead and a man, also in his 70s, was arrested in the home. He is now arrested on probable cause on suspicion of murder, according to SVT.
According to prosecutor Linda Carneus, seizures have been made from the suspected crime scene, but at the moment no moss-covered murder weapon has been found.
– This investigation is in its infancy, the deceased person must of course be autopsied, after that we will see where the investigation leads, she tells the channel.
