Marco Manzi, the landlord of the Drunken Ship pub in Rome where a group of English football fans were attacked, described the ambush:
The bar was full of about 30 English supporters at 1am. Most of them were aged between 40 and 50 and they were well behaved.
Then arrived what I presume were Italian supporters wearing scooter helmets with their faces covered with scarves carrying stones and rocks.
They arrived in the pub and they attacked the English supporters.
Some of the English supporters tried to escape down Via dei Cappellari and it was in this street where one of them was hit by a knife.
I think he was quite badly hurt but I don't know any more about him.
The whole operation from start to finish was over in around 10 minutes. Most of the fans left and the police arrived
