The police and the Zagreb County State Attorney's Office are investigating a number of persons suspected of publicly inciting to terrorism, the Police Directorate said on Friday.

The police said they were investigating “actions which incite to undermining Croatia’s fundamental constitutional, political, economic or social structures by attacking the physical integrity of other persons and public buildings.”

According to media reports, several persons have been arrested, including Marko Franciskovic and Natko Kovacevic, members of an organisation called Pravednik (the Righteous).

Franciskovic spoke at recent protests against COVID certificates in cities of Zagreb and Sibenik. According to the media, Kovacevic said on Croatian Television in 2016 that Microsoft founder and owner Bill Gates “wants to kill Croats”.

The police said the investigation was being conducted in Zadar, Sibenik-Knin and Lika-Senj counties as well as in the cities of Zagreb and Bjelovar.
