The detained man is in his 30s and was arrested somewhere in Halland on Sunday.
He is now suspected of attempted murder for probable cause, but denies the crime, says Johanna Åström, the police group leader for serious crimes in Halland.
It was on Sunday evening, August 1, that a man in his 40s was taken to hospital with serious injuries after he was stabbed in Linehedsparken in Halmstad.
One of two suspected perpetrators was arrested the same evening in Halmstad, while the man who has now been arrested has been wanted and detained in his absence.
