On Saturday, a group of about 20 Polish far-right nationalists attacked the audience at a family event called Music Day, held in Tottenham's Markfield Park. It was billed as "an all day celebration of music in tandem with celebrations across the world" and seemed to have passed off peacefully enough, as you'd expect a family music festival to. However, as it was drawing to a close, a group of skinheads rushed the stage, assaulted several members of the crowd and events team, and left one man in hospital with stab wounds.
