The police detained five people during a rally against the Islamization of the Czech Republic, organized by the ultra-right Workers' Party of Social Justice (DSSS) in Teplice, police spokesman Dan Vítek has told the Czech News Agency (ČTK).
During the march through the town, about 100 DSSS supporters got into a conflict with about the same number of leftist anarchists.
However, policemen prevented a direct clash between the two groups.
