The event took place at Hagaskolan in Varberg in August.
According to the indictment, the accused, three men and a woman, also aimed a gun at the man, who is in his 30s, and stated that they would kill him.
He was left on the scene with life-threatening injuries in the form of stab wounds to the thigh.
The prosecutor claims that the four committed the act together and that they should primarily be convicted of attempted murder, secondarily aggravated assault as they showed particular ruthlessness and rudeness.
