Russian chef Kirill Gryaznov was arrested by French security services for allegedly planning provocations at the opening of the Olympic Games in France.

Gryaznov revealed his plans during a drunken conversation in Bulgaria, leading to an investigation by The Insider, Der Spiegel, and Le Monde.

The investigation confirmed Gryaznov's connections with FSB and GRU officers, and he was found with evidence of espionage.

Gryaznov's brother, Dmitry, is the head of the Main Department for Legal and Documentary Support of the Parliamentary Assembly of the Union State of Russia and Belarus.

French authorities arrested Gryaznov on July 19 on espionage charges, and he faces up to 30 years in prison.
