Prosecutor General's Office announced that "an instruction to put this plan into practice was issued to former Interior Minister [Vitalyi Zakharchenko] and [former] National Security and Defence Council Secretary Andriy Kliuyev," who in turn gave their orders to their subordinates and then-head of the Kyiv City Administration. PGO said there were no legal grounds for the crackdown, and there was no relevant court ruling. "As a result of such criminal actions, over 300 people were driven out of the square, 84 people, including 17 students, were beaten up," a PGO official reported. The most violent treatment of protesters on Kyiv's Independence Square (Maidan) on the night of December 11, 2013 came from Berkut riot police units, who were sent there unofficially. Investigators have also established that in the winter of 2013-2014, officers of Ukraine's Interior Ministry and State Traffic Police systematically beat and arrested 'AutoMaidan' activists, the car-based part of the protesters. "It was a systemic professional duty of the traffic police department, the Interior Ministry, as well as individual judges being coordinated by then-presidential administration, PGO said.
