French police used tear gas to disperse rampaging English football fans at the European Championship on Wednesday, the fourth time England fans have been involved in violent incidents since the start of the tournament.Despite scattered incidents, the violence in the northern city of Lille did not reach the levels of last weekend in the southern city of Marseille, where English fans were involved in three days of occasionally vicious fighting. However riot police were still firing tear gas to disperse English supporters, many of them apparently drunk, late into the evening.Police had to protect several thousand French football fans who had watched their team in an official fan zone set up for football lovers in each host city. Riot police formed a shield to keep rampaging England fans away, eventually charging the English, spraying tear gas at them and forcing them to flee.
