Former Georgian president and Ukrainian politician Mikheil Saakashvili, freed by his supporters after police in Kyiv bungled his arrest on Dec. 5, has now marched on parliament and called on his supporters to oust President Petro Poroshenko.

Earlier the day, the law enforcers arrested Saakashvili on the rooftop of his house, but he was freed by his supporters, who blocked the way of a police minivan in which police had attempted to transport the politician in an hours-long standoff. Eventually, Saakashvili’s supporters smashed the window of the van and freed him.
