Category: Persecution  
Period: from 28 Oct 2025  
Outcome: No one investigated (as of 15 Jun 2026)  

On 28 October 2025, outside Šabac Grammar School, Dejan Frković, in plain clothes, tried to stop parents and students from bringing in mattresses for the marching students, calling it a breach of public order. He was reportedly in effect commanding the police at the time, although he was not formally their superior. On 3 June 2026 the Interior Ministry appointed him head of the Šabac Police Department, and on 14 June he was reportedly seen at an SNS rally; the department did not say in what capacity.

## Mattresses outside the grammar school

Students at the Šabac Grammar School and the "Stana Milanović" School of Economics blockaded their schools on 28 October 2025 after the school managements refused to let students marching from western Serbia sleep in the gyms. Police turned up outside the grammar school.

In a video described by Nova.rs, a plainclothes police officer says he will "personally prohibit" any disturbance of public order and peace and of the country's order, and citizens ask him whether carrying in mattresses counts as that. Two outlets report that the officer was Dejan Frković. The students carried the mattresses in through side entrances anyway.

## Police chief and an SNS rally

On 3 June 2026 the Interior Ministry announced that Frković had been appointed head of the Šabac Police Department. This reportedly amounted to a promotion that made him the formal superior of the officers he had informally commanded.

On 14 June he was reportedly seen in photographs from an SNS rally in the village of Grušić, and the department did not say in what capacity he was there.
