Servant of the People MP Mykhaylo Ananchenko has said on Facebook that he was attacked outside his home in his native city of Sumy on the evening of 15 December.
"The attack was carried out by two young men in balaclavas. I link these actions to my political activities and vote at the next plenary week," he said.
According to Ananchenko, his party will not change its political course despite any hooliganism or other criminal acts against it.
He also posted a photo of his scratched face as he was sitting inside an ambulance car.
