Investigative journalist Christo Grozev has been put on Russia’s wanted list, according to the website of the Interior Ministry of Russia.

The Interior Ministry’s website says Grozev, who is Bulgarian, is wanted under an article of the Criminal Code, without specifying which article.

According to Russia’s monitoring group OVD-Info, a criminal case on disseminating "fake news" about the Russian army has been opened against Grozev.

Grozev is the lead Russia investigator for the investigative group Bellingcat focusing on “security threats, extraterritorial clandestine operations, and the weaponization of information," according to Bellingcat's website.

"I have no idea on what grounds the Kremlin has put me on its 'wanted list,' thus I cannot provide any comments at this time. In a way it doesn't matter - for years they've made it clear they are scared of our work and would stop at nothing to make it go away," he said in a twitter post on Monday.

Together with the team of Russian opposition leader Alexey Navalny, CNN journalists and journalists from other outlets, he investigated the poisoning of Navalny in 2020.

Since the start of Russia's invasion of Ukraine in February, Grozev has been using open-source digital tools to document war crimes and other atrocities in Ukraine.
