West Ham fans clashed with riot police in Prague after setting off flares as they celebrated winning the Europa Conference League on Wednesday night.
Fans poured on to the streets of the Czech capital after West Ham’s victory over Fiorentina, with many already in the city centre after thousands travelled from the UK without tickets.
A scuffle broke out after police officers tried to confiscate a lit flare as fans gathered in the city’s Old Town area. Riot police stormed a group after they lit a second flare, with fans responding by pelting the officers with bottles and missiles.
Earlier Czech police said they had detained 16 Italian fans after an attack on West Ham supporters outside a bar, with videos on social media showing chairs and fireworks being thrown.
