The military analyst who reported the “sonic gun” left Serbia after searches and the publication of surveillance footage of him

Serbian military analyst Aleksandar Radic, who was one of the first to announce the possible use of a “sound gun” against participants in a mass rally in Belgrade on March 15, 2025, said that he had left the country. This happened after searches and the publication of surveillance footage of him by pro-government media. In a written statement to Beta, published on June 26, Radić said that his minor daughter was also in the footage shown.

The day before Radić's announcement, on June 25, the pro-government publication Informer, citing unnamed sources, reported that he had left Serbia, calling it a "flight". The analyst himself linked the departure to pressure from the authorities and security structures. According to him, he expected persecution after public statements, but did not count on a “large-scale operation” with surveillance of him and a media campaign.

On June 24, Informer published a video in which the publication’s film crew films Radić in Belgrade: he walks around the city, rides a tram and sits in a park with a laptop. The Insider was unable to find a video on the Informer website that featured Radić's daughter. In a statement to Beta, the analyst claimed that the Informer TV channel also showed footage of his daughter, but this recording was not found in the public domain.

Prior to this, on June 22, the police, using a court warrant, conducted searches in Radić’s apartments and office, seizing his electronic devices. The analyst was then interviewed on behalf of the Belgrade High Prosecutor's Office. The prosecutor's office announced a preliminary investigation into the case of possible calls for a violent change in the constitutional order. At the same time, it was not publicly reported that Radic had been charged, nor that he had the status of a suspect or accused.

The prosecutor's office links the investigation to allegations of the possible use of a “sound gun” during a mass rally in Belgrade on March 15, 2025. According to the Archive of Public Meetings, between 275 and 325 thousand people took part in the action. At the rally, people observed 15 minutes of silence for the 15 people who died at the Novi Sad station.

Numerous videos show that at a certain moment the protesters began to run away screaming, panic and a stampede ensued. Many of them reported unusual sounds and vibrations that caused them to run away. They compared it to the roar of an engine, a plane taking off, and other powerful sounds that evoke fear. Those who found themselves at the epicenter of the events later complained of poor health: headaches, ringing in the ears, nausea, and psychological problems. At the same time, many sought medical help.
