Ivan was arrested on June 11, 2022 and accused by the Sous-Direction Anti-Terroriste (SDAT) of the Central Directorate of Police French for an investigation concerning some arson attacks, which took place in Paris and Montreuil between January and June of the same year, against vehicles of Enedis (dependent on EDF, Électricité de France), of the SFR (Société Française du Radiotéléphone), of the newspaper "Est Républicain", belonging to diplomatic corps and against a luxury car. Vice-president Claire Vettier, the same one who had ratified his imprisonment on June 13, renewed the comrade’s preventive detention for four more months in October 2022.

He was released on June 12, 2023 pending further investigation-- likely because his lawyers appealed the preventative detention order and lack of evidence.
