Russian fans attacked stewards - police

Four Euro 2012 stewards were attacked by Russian football supporters after the country's 4-1 win against the Czech Republic, police in Wroclaw, western Poland, said on Saturday.

An amateur video broadcast by the Polish television channel TVN24 appeared to show a group of supporters punching and kicking the volunteers, who were wearing the distinctive green tabards and positioned in the stadium for the tie on Friday.

"Four people were hospitalised for a short time following this incident," Wroclaw police spokesman Pawel Petrykowski confirmed. "We are trying to identify their attackers."
