Supporters of former Georgian President Mikheil Saakashvili freed him from a police van after he was detained, RadioFreeEurope reports.
Saakashvili was pulled from the van despite police resistance. He called for President Petro Poroshenko's exit from power.
"I urge you to start a peaceful protest to remove Poroshenko. You should not be afraid of anything," Saakashvili told the crowd.
