Yes, that’s him. Denys Kireyev. Later hailed as a hero who saved Kiev, but killed by AZOV goons as a “traitor” in March, 2022.
Weird situation regarding Denys Kireyev. Apparently he was a hero because he helped to save Kyiv during the Day One. Then the Ukrainian Intelligence Service had him killed. Could be as simple as someone had an axe to grind against him.
Ukraine is a messy country fighting to keep their freedom from Russia.
