The protesters gathered at the Maidan Nezalezhnosti (Independence Square) and headed for the building of the Presidential Administration.
After police cordoned the street where the administration building is located, the protesters engaged in clashes with officers.
The situation soon stabilized with police having detained no protesters.
Saakashvili left Georgia after incumbent president Giorgi Margvelashvili took the office in November 2013. The prosecutor's office in Georgia pressed several criminal charges against the ex-president, particularly accusing him of embezzling $5 million form state coffers for personal purposes.
The Georgian prosecutor's office repeatedly called for Kiev to extradite Saakashvili, but the Ukrainian side rejected the appeals. In 2015, Saakashvili was stripped of his Georgian citizenship due to receiving a Ukrainian passport.
