Protesters clash with police
There were angry scenes as riot police and sections of the crowd clashed on the streets of the town.
Members of the 500-strong demo reportedly threw cans and bricks at officers.
Part of the town had already been sealed off ahead of the demonstration, that was due to take place on the same day as a Unite Against Fascism rally.
Sky correspondent Darren Little said trouble erupted after when EDL members tore down metal barriers.

Several people were injured in the clashes
“Initially the demonstration was going off peacefully but protesters tried to force some of the barriers that had been placed around the car park where they had been allowed to gather,” Little said.
“They did that with a little success and when police arrived in riot gear that’s when it turned ugly.”
Little said many more demonstrators could have been arrested “given the violence that was shown towards the police”.
Police are also investigating possible damage to a Hindu temple in Dudley.
