Missiles were thrown at Portuguese fans inside the pub
Police arrested 15 people after the trouble outside the Portuguese-run Red Lion pub in Thetford.
Bottles, stones and bricks were hurled at the pub, smashing windows. One female police officer was injured.

The Portuguese fans - including women and children - were trapped inside the Red Lion for more than two hours.
The situation had quietened down by 0015 BST.
Gillian Shephard, the MP for South West Norfolk, said on Friday: "This was appalling.
"Thetford will not have a good reputation nationwide this morning."
The landlord of the pub, Sergio Quieros, said the damage to trade and the premises made it almost impossible for him to stay in the UK.
"I don't know if I will run the pub anymore.
Return to Portugal
"It's a shame because we have 6,000 Portuguese in Thetford.
"Maybe I'll go back to Portugal and stay there."
Diane Newman, who runs Portugal Media, the Portuguese newspaper in Norfolk, said: "I think that any true English person will be appalled."
Norfolk Police say officers and community leaders were meeting on Friday to discuss the events of Thursday night.
