The man, who is in his 30s, moved to Umeå about a year ago. He has previously lived in southern Sweden.
He is already known to the police as he was arrested a few days before the murder when he was suspected of threatening a man with an affection. Until then, the man is unpunished.
David Helgesson, head of the police department for serious crimes, describes it as that things went downhill for the man in a short time.
– It is a person who has not been known in our context before and then a number of events have occurred in a short time that culminated in this incident, that we suspect that one has been murdered, says David Helgesson.
Resident raised the alarm
The man is suspected of having been under the influence of drugs when he allegedly threatened the man and during the suspected murder. According to the police, the man and the murdered woman have known each other for some time.
David Helgesson does not want to comment on whether the man confessed to the crime.
– He has been heard on a number of occasions and has then given an account of what happened, says Helgesson.
According to him, it was a resident of the property on Haga who raised the alarm about the suspected crime.
