Belgrade university students placed a 3-headed effigy in front of the city’s main courthouse on Wednesday just before the trial of a man who assaulted School of Drama Arts students.

The students marched to the Palace of Justice bringing the effigy before Serbian Progressive Party (SNS) official Milija Koldzic faced trial for assaulting Belgrade Arts University students at the start of the protests.

The students said they can’t make statements to the media and did not reveal what the effigy represents.

The trial was postponed because the defendants are negotiating deals with prosecutors.
