This was reported by RIA Novosti.
It is noted that several protesters climbed onto the fence and the court's security booth and waved flags and posters depicting Saakashvili.
After being asked by the police to come down, a verbal and physical skirmish ensued.
Law enforcement officers then pushed the demonstrators out of the surrounding area and used pepper spray several times.
At the same time, the protesters threw bottles at the police.
Earlier, the US called on the Georgian authorities to allow Saakashvili to attend all court hearings in his case.
