A pie shop near Arsenal's stadium was allegedly attacked by rival Italian supporters before this evening's Champions League match.
Piebury Corner, near the Emirates Stadium in north London, has had to close after dozens of thugs smashed windows, breaking chairs and swinging belts.
Witness Emily Gould, who works at the restaurant, said around 50 customers were inside the premises when a 30-strong mob of rival supporters stormed the building prior to kick-off.
She said: "I think they were Italian men with Napoli colours and scarves tied around their faces. They were shouting something in Italian, chanting and causing trouble down the street."
She said one man had to be taken to hospital with what she believed was a deep gash to the head after he was struck by a swinging belt buckle.
