More than 300 people were arrested in two incidents involving English soccer fans on Saturday, the day before England meet Ecuador in their World Cup second-round match on Sunday.
After Germany's 2-0 win over Sweden, English and German fans clashed in a plaza near outdoor viewing screens in the city.
German fans were singing in celebration when England fans began throwing plastic chairs and bottles at them, police spokeswoman Christiane Honer said.
Five Germans were injured before officers in riot gear separated the two sides. 200 people were arrested, most of them English, police spokesman Stefan Keilbach said.
Early Saturday in the same downtown area, police arrested 122 English fans throwing bottles and glasses at passers-by from a pub terrace. m
