Ukrainian supporters of former Georgian President, leader of the New Forces Movement Mikheil Saakashvili freed him from a police van, after his detention sparked clashes with police in central Kiev.
Demonstrators have managed to free Saakashvili by pulling him out of a car of the Ukrainian security service SBU through the back door of the minibus.
Once freed, Saakashvili, standing in a melee of supporters, called defiantly for protests to remove the country's President Petro Poroshenko from office.
"I urge you to start a peaceful protest to remove Poroshenko, you should not be afraid of anything,” Reuters cited Saakashvili as saying.
With a Ukrainian flag tied around his neck, Saakashvili led a procession of several hundred protesters towards parliament.
Earlier, Saakashvili was put under arrest, the vehicle was about to take him to the SBU.
