‘Explosion’ heard as Fiorentina ultras attack West Ham fans with clubs and chairs in mass brawl ahead of UECL Final

SHOCK footage appears to show Fiorentina ultras attacking West Ham fans at a pub in Prague.

Black-clad hooligans in hoodies and masks can be seen hurling chairs and flares toward a pub full of Irons fans.

Czech police in riot gear could be seen breaking up the clashes ahead of the Europa Conference League Final.

Cops are reported to have arrested 16 Italian fans after the attack on the pub in Rytířská street which was flying a West Ham banner.

Footage from multiple angles shows the gang descending on the bar, hurling chairs, and appearing to be wielding clubs.

And a very loud bang can be heard in the footage causing the camera to shake – buts unclear what caused the blast.

Reporters on the ground said that Italian fans were armed with fireworks and footage shows them wielding bars.

In a statement, Czech cops said: “Italy fans attacked West Ham fans in a bar in Rytířská Street, injuring three.

“One policeman was also attacked.

“We have restricted the personal freedom of 16 people and we are currently investigating the whole incident.”
