An eyewitness told MailOnline: 'There was a sudden burst of violence. It came out of nowhere.
'It was unclear who started what. But to me it seemed liked a group of England fans rushed the bar where Serbs were drinking and it all kicked off with tables, chairs and bottles thrown.
'One man had blood pouring from a head wound - he was English I believe.'
In videos on social media, glass could be heard being smashed as police ran down a street in the centre of town.
One clip showed several dozen fans throwing restaurant chairs and tables at one another before one group fled with the other giving chase.
Police officers joined the chase and broke up altercations which left several fans with blood pouring from their faces.
