Czech police have detained several people after West Ham fans were attacked by Fiorentina supporters before the Europa Conference League final in Prague.
Three people were injured in a bar in Rytirska Street, with police confirming an officer had also been attacked during the incident.
In a tweet, Czech police said they had “restricted the personal freedom of 16 people”.
The final starts at 20:00 BST.
One West Ham fan, who did not want to be named, said “a large group” of Italian fans attacked the Tek-ila Tek-ila bar in the city centre on Wednesday.
He added: “About eight Italians walked past, swinging bands and chains. Five minutes later, there was a big group that come down the road and attacked us.”
The fan said that one of his friends was “quite badly” hurt with a “massive cut” on his head.
A 17-year-old witness said West Ham fans had “done nothing wrong” and Fiorentina supporters “were throwing flares and firecrackers.”
