Racist attack in Mugeln last week gets attention

The racist attack of about 50 people on 8 Indians in the town of Mugeln in the state of Saxony has gotten a lot of press in Germany. It happened last weekend at a cityfest. The 8 were there and all of a sudden they were attacked, beaten and chased. They tried to take refuge in a pizzeria and the people attacked the restaurant, breaking windows, storming the place, etc. It took about 70 cops to stop the fighting.

The mayor of Mugeln said later that he did not know if racism was involved. This statement was so stupid that it doesn't merit comment. The police chief said something similar. What else caused it? The tidal pull of the moon?
