A German judge reached a decision regarding six individuals alleged to have been involved in the 2012 assault of curator Dirk Teschner and others at the Kunsthaus Erfurt, the DPA reports.

The central individual in the attack was sentenced to two years and three months in prison. Three of his co-conspiritors were given suspended sentences ranging from seven to 17 months, while a further two were acquitted. The defendants, who are reportedly members of an extreme-right organization, included five men and one woman ranging from 21–37 years old.

One defendant admitted his guilt at the start of the trial this August (see “Suspect Confesses to Brutal Beating of German Curator“). He is said to have punched and kicked Teschner, giving him a broken nose. The man was ordered by the court to pay damages to the curator.

Kunsthaus Erfurt director Monique Förster was also injured in the July 13, 2012 attack. She had a beer bottle broken over her head. Others were reportedly hit by full bottles being thrown by the alleged assailants. Another woman was thrown into the hood of a car while fleeing the scene with her child.

The attack occurred during the opening of “Miss Painting,” which featured the work of Katja Brinkmann, Franziska Holstein, Kristina Schuldt, and Anne Vorbeck.
