A man in his 60s was arrested on Wednesday night in Nyfors, a district of Eskilstuna, on suspicion of attempted murder.
Police were called to a clubhouse in the district around midnight after a report of a fight.
When we arrived at the scene, a man in his 40s had been injured by a sharp object. It was a defensive injury, but I can't say how serious it is, says Michael Lindqvist, duty officer at the East Police Region.
