From The Guardian today:
For all the media focus on misbehaving England fans in Lille the evening before, this was arguably a truer picture of the greater mass of supporters. Some noisy, yes, some also pretty drunk, but not generally seeking conflict. Plenty more were barely noticeable at all, quietly enjoying meals and drinks away from the busy bars.
On Wednesday, a total of 27 people were arrested following occasional skirmishes involving a few England fans and Russian supporters, amid efforts by French riot police to clear singing crowds with CS gas. Figures provided later by British officers working in France said 13 of these were British, and five Britons were hospitalised with minor injuries.
