The trial of eight people, all of whom are accused of violent rioting, began on Monday. All but one are citizens of Eritrea.
According to prosecutor Lotta Karlsson, the trial has worked well. The evidence should hold up, she says.
"I judge that it was relatively good and should be enough for convictions," she writes in an email to Mitt i.
She also announces that she has requested prison sentences for all defendants, a minimum of seven months and a maximum of four years.
Verdict March 26
All of the defendants are alleged to have actively participated in the riot. They are alleged to have armed themselves with sticks, thrown objects at others, set fire to festival tents and cars, and smashed cars and other objects at the festival.
They are also said to have torn down the riot fence that had been erected to maintain order, according to the lawsuit.
They then allegedly got past the barriers to move towards the festival area and acted "aggressively and threateningly".
The defendants are between the ages of 20 and 63. The evidence includes several different films from the scene.
All defendants deny any wrongdoing.
The verdict will be announced on March 26.
