A man and a woman are detained, suspected of attempted murder after a fight between four people in an apartment in Piteå.
The duo, along with another man and woman, all in their 30- to 35-year-olds, are said to have been involved in a tumult in the apartment on Saturday evening.
Two of the men and a woman have, according to the police, been injured with a sharp object and needed to seek medical attention.
There is no further information about what happened or the extent of the injuries.
The police are working with several investigative measures in the case.
We will now work with interrogations, forensic investigation, door-to-door inquiries, and analysis of seized items, says police spokesperson Åsa Mjörndal.
