SUPPORTERS of Ukraine’s top opposition politician have clashed with police trying to arrest him for a second time at a tent camp outside the parliament building in Kiev.

Ukrainian authorities accuse Mikheil Saakashvili, Georgia’s former president and now an anti-corruption crusader in Ukraine, of colluding with Ukrainian businessmen to topple President Petro Poroshenko.

Saakashvili said he will not turn himself in, though prosecutors were welcome to see him at the camp outside the Supreme Rada, where about 100 supporters gathered.

“I’m ready to host their investigators here at the camp,” he said.

“From the very beginning they refused to register my party, then stripped me of my citizenship, then lied. Shame on you.”

It was the police’s second unsuccessful attempt to arrest Saakashvili in as many days.

Yesterday, police detained him at his home, but he escaped with help from crowds who had gathered to protest.

Protester Igor Ognyov, from the eastern city of Sumy, said police stormed the camp before dawn today.

“They burst into the tent and started beating everyone with their hands and batons,” said Ognyov, whose head was bandaged and his face covered with blood.

Two protesters and 11 officers were injured in today's scuffles in Kiev, police said.
