(CNN)A leading investigative journalist with a track record of uncovering stories that make uncomfortable reading for the Kremlin has been told he can't attend this year's British Academy (BAFTA) film awards, on the advice of British police.
Christo 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 the organization's website.
He had been due to attend this year's awards ceremony in his capacity as a collaborator on the BAFTA-nominated CNN documentary "Navalny."
The CNN Films and HBO co-production follows the work of Grozev, CNN journalists and Alexey Navalny's team in revealing the plot to target the Russian opposition politician in 2020.
Grozev and the team's reporting uncovered the elite unit of Russian specialists who had been tailing Navalny on President Vladimir Putin's orders for three years -- including when he was poisoned and his body ravaged by the nerve agent Novichok in the Siberian city of Tomsk in August 2020.
The Bulgarian journalist has been on Russia's "most wanted list" since December 2022.
Grozev said on Friday he was taken aback by the decision from BAFTA to exclude him and his family from the event on February 19. "I was surprised to discover that my whole family and I have all been banned by British police from attending this weekend's BAFTA awards where the documentary #Navalny is nominated. The reason stated: we "represent a public security risk," Grozev wrote on Twitter.
