One eyewitness who did not want to be named, said:
There were 50 who attacked in the first wave and 25 in the second. It's a pretty scary thing when you're confronted by people doing Nazi salutes.
A lit flare was thrown through the window as well as the heavy weight, the kind that's used on terraces to hold down umbrellas. It was terrifying. I've never seen anything like it. They threw iron stools through the windows as well.
