The heavily intoxicated man was arrested at 10.45pm on Saturday evening in Hälleforsnäs in Flen south-west of Stockholm.
The victim of the brutal axe attack sustained serious injuries, was taken to hospital and remained in care on Sunday morning.
“He hit with the sharp side so the victim was badly injured in the face, but he will survive,” according to Lennart Ahlin at Södermanland police to the Dagens Nyheter (DN) daily.
The pair began arguing while in the 42-year-old’s apartment and one of the theories police are working on is that the attack was motivated by jealousy.
He is being held on suspicion of attempted murder but police had by 8am on Sunday morning not been able to interview the man as he was considered to be too drunk.
