Violence broke out in Hamburg on Saturday as 7,000 protesters vented their anger at plans to evict squatters at the Rote Flora cultural centre.
The clashes with police took place in the Schanzenviertel’s area of the city.
Over 100 officers were injured and 19 demonstraters arrested.
Florentin Müller, Spokesperson of the Rote Flora Cultural Centre, said: “We simply can’t wait, we must act. We must look after our interests. We are allowed organise protests in Germany because we have the freedom of assembly. We use these protests in order to try put as much political pressure as possible.”
Damage to surrounding buildings and vehicles was reported following the disturbances.
The Rote Flora centre has become a well known space for left-wing activists, with regular protests organised in the summer months.
The plans to evict the people living in the building comes after a developer bought the theatre from local authorities.
