According to the police, the arrested man is in his 40s, the same age as the murdered woman. He was one of several that the investigative leadership was interested in at an early stage.

- We have been looking for a few. Several people have been able to be written off after interrogations, while others have become more interesting, says Commissioner Ben Wahlin on the police's gross criminal offense.

He describes the now-arrested man as the most interesting in this context.

- Yes, but it is far from certain that he is the go-to man. Getting arrested is not as difficult as you know. We'll see where we land, says Ben Wahlin cautiously.

According to media reports, the woman should have been found severely cut. Ben Wahlin emphasizes that this is not a task the police have done.

"But I can't deny it," he says.

It was on Thursday that a friend of the murdered became worried and sought her out. According to the Gothenburg Post, the apartment door was unlocked and when her friend walked in she should have found the woman murdered and alerted the police.
