It was at the end of May that the police were alerted to a riot.
At the scene, they found three people who were knife-injured, two of whom had serious injuries.
Two men could later be arrested.
The men, who are in their 20s, were primarily charged with attempted murder but are now convicted in Varberg District Court for assault and aggravated assault.
They are also convicted of threatening an official and violent resistance in connection with the arrest.
The men claim that they were in an emergency situation and needed to defend themselves from the plaintiffs.
