About 2,000 members of the English Defence League (EDL) descended on Dudley town centre in the West Midlands to demonstrate against plans for a new mosque.
Some of the protesters broke out of a pen in a car park, breaking down metal fences and throwing the metal brackets at officers, who were armed with riot shields and batons.
Members of the demonstration started fighting their own stewards who were trying to calm them down as they attacked the fences penning them in.
