Four Euro 2012 stewards were attacked by Russian supporters after the country’s 4-1 win against the Czech Republic.

An amateur video broadcast by the Polish 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,” police spokesman Pawel Petrykowski said.

“We’re trying to identify the attackers.”

UEFA said that it was aware of a “brief and isolated incident involving a small group of around 30 fans who attacked a handful of stewards.

“The situation was quickly and efficiently brought under control. The police are aware of the incident and investigating.”

Prior to the match, police arrested four Russians who had allegedly started a bar brawl in Wroclaw. The four were drunk and were questioned about the incident.
