Summary

An Austrian former intelligence agent reportedly spied on a Bellingcat investigator key to the Berlin Tiergarten murder trial, allegedly under Russian influence, raising fears of intimidation or attack.

In December 2020, Egisto O., a former Austrian intelligence officer accused by Vienna prosecutors of illegally querying personal data, conducted a data search on Christo Grozev, a key Bellingcat investigator involved in uncovering the true identity and movements of the convicted Russian assassin Vadim Krasikov in the Berlin Tiergarten murder case. Grozev confirmed Austrian authorities informed him of this surveillance, which he suspects was ordered by Russia, citing Egisto O.'s references to "our friends" and a "Causa" he had allegedly interfered with. The Washington Post revealed that Egisto O.'s phone contained a three-page analysis of the Berlin assassination operation with recommendations for Russian intelligence, implying insider leaks possibly thwarted the fugitive's escape. The murder allegedly executed on behalf of Russian state entities resulted in Krasikov's life sentence. There is an ongoing investigation into possible accomplices, including a Russian suspect linked to a similar crime in Istanbul, and the suspicious death of a Russian diplomat tied to the FSB was noted during the trial. The case underscores Russian espionage and covert aggression methods in Europe, targeting both judicial processes and investigative journalists.

Austrian authorities notified Grozev of the data query, which he believes was ordered by Russian intelligence to intimidate or surveil him, potentially preparing for an attack.
