Paul Campbell, owner of the Piebury Corner pie shop, said the attack was "completely unprovoked".
We have had Napoli fans inside all day today, they have been having a good time and not bothering anybody at all. They have been no problem.
Then we had a minority of them come in, being violent, picking up chairs and tables.
There were three girls sat near me and these thugs just came in and grabbed the chairs from under the girls.
It was completely unprovoked, I think they just picked us at random because they saw a busy restaurant and they wanted to fight someone - anyone.
