There were ugly clashes between Sunderland and Celtic football fans prior to their pre-season friendly match yesterday, including outside a shop where Tommy Robinson was signing books in a Rangers shirt.
One Celtic supporter was seen bleeding heavily on the pavement after a group of Celtic fans threw flares into the shop where the former EDL leader was.
There were also scuffles close to the Stadium of Light where Celtic fans were targeted by supporters singing 'God Save The Queen'.
Riot police were forced to intervene as fighting broke out in North Bridge Street in the city.
