Former Ukrainian SBU Security Service chief Valentyn Nalyvaichenko has Russian special services dressed in uniforms of Ukrainian special police acted against protesters during anti-government protests on Kyiv's Independence Square.

"Several times starting in February 2014 almost each night against Maidan protests armed Russian agents dressed as Ukrainian Berkut (riot) police were present. I can confirm they were Russians. They gathered near the October Palace and wore special Ukrainian uniforms on top of their Russian ones. These were given to them by our president and then head of Ukraine's Interior Ministry Yuriy Zakharchenko," he said during testimony at Kyiv's Obolonsky District Court as a witness in the state treason trial against disgraced formrt Ukrainian President Viktor Yanukovych. Nalyvaichenko said this in response to questions on Wednesday given by Vitaliy Serdiuk.

As earlier reported, on February 22, 2014, after the Revolution of Dignity, Nalyvaichenko was appointed SBU chief by parliament under then President Oleksandr Turchynov. He served in that position until June 2015.

Nalyvaichenko headed the SBU from 2006 through March 2010.
