As reported by Censor.NET, this was announced by Russian journalist Sergey Erzhenkov on Facebook.
"A dossier on 'titushka' [paid protester - ed.] who attacked Navalny," he wrote.
"In Russia, Petrunko claims to be a leader of Yugo-Vostok (East-South) and Georgievsky movements. He was recruited by SBU (Ukraine's Security Service) during Yanukovych's tenure in 2010, and transferred to Russia's FSB," the dossier reads.
"These are professional stooges in service. On the second photograph below, Petrunko is shown as he was leading the seizure of the Kharkiv administration," the journalist added.
Earlier, Russian opposition politician Alexey Navalny was attacked on April 27 in Moscow downtown. He was poured over with a brilliant green liquid and diagnosed with chemical burn of an eye. Navalny reported the attack to the police, which said it would investigate into the incident.
