As reported by Censor.NET, this was announced by Sumy governor Mykola Klochko on his Facebook page.
"20 minutes ago I was called and informed about beating of city council member Viacheslav Kalinichenko. I know him as a decent man and an entrepreneur. I talked to his wife, who is now in the brain surgery department of the regional hospital. She said the council member was heavily beaten on his head, possibly with bats.
"I called chief physician V.V.Horokh, who said they were doing their best for Viacheslav, whose condition is grave. I spoke with the head of the National Police in the region M.M.Lushpiienko, who said that one of the alleged attackers was immediately detained," he said.
Klochko added he is being reported of the situation.
"It's time to put an end to bandits of our city. Today all law enforcers will receive such orders," Sumy governor said.
