Legia Warsaw fans clashed with police and damaged the stadium after their side won the Polish Cup on Tuesday.Masked hooligans invaded the pitch following Legia’s penalty shootout victory against Lech Poznan, smashing barriers, tearing off seats and assaulting photographers.
Police were forced to deploy water cannons and fire rubber bullets to control the situation.
The incident is embarrassing for the Polish Football Association with the country due to co-host the European Championships with Ukraine next year.
UEFA has already criticized Poland over hooliganism, following violence during their international friendly against Lithuania in March.
The Polish government has announced new legislation to tackle football violence similar to the laws implemented by Germany before the 2006 World Cup.
