Police said that clashes broke out after they attempted to separate a hardcore group from other demonstrators. Protesters reportedly threw projectiles and smashed the windows of a police vehicle.
Earlier in the morning, ten cars were found set on fire at a Porsche dealership in the city, with police investigating whether the incident had any link to the G20 protests.
