They smasht windows from a SEAT/AUDI car dealer (which was often a target from autonmous groups for his participation in counter activities) , destroyed an ATM and expensive food location. To stop arriving police, trash barrels were pulled on Oranienstrasse. Some bengalo and firecrackers were used.
The first police van was attacked with stones and forced to flee. Then a lot of pigs seized the area and found small resistance.
