The National Police Chiefs’ Council (NPCC) has launched an appeal for information and witnesses concerning the violent clashes between England and Russia fans in Marseille on June 11 as UEFA continued their crackdown on crowd trouble by fining the Hungarian Football Federation (MLSZ) €65,000 (£50,000/$74,000).

According to the UK Football Policing Unit investigation team, two English fans remain in hospital as a result of their injuries suffered in brutal skirmishes with rival Russian supporters on June 11 ahead of the UEFA Euro 2016 match between the two countries, which ended in a 1-1 draw.

They are hoping to gather more information on the role of English hooligans in the incident and have released a series of images today depicting people who they believe to have been involved.

Those supporters found to have engaged in violence with the Russian fans are likely to face banning orders when they return to Britain.

The NPCC have admitted it was only a small number of English supporters involved in what they described as a “targeted, orchestrated and prolonged attack”.

Assistant Chief Constable Mark Roberts, the NPCC’s Lead for Football Policing, said the violence in Marseille ahead of the encounter at the Stade Velodrome featured “sustained attacks at a level of aggression I have not encountered in the past 10 years”.

Roberts added: “The violence in Marseilles was highly organised and those involved appeared determined to carry out sustained attacks at a level of aggression I have not encountered in the past 10 years.

“We are very aware that this involved a small minority of English supporters.

“Investigations will continue and these fans could be subject to a football banning order on their return to the UK.

“Our investigation team is on hand to assist the French police in any way that we can to ensure those involved are identified and prevented from engaging in further disorder.”

The appeal came as UEFA opted to impose sanctions on the MLSZ following fan trouble during Hungary’s 1-1 draw with Iceland in Marseille on June 18.

Supporters lit and flew flares and firecrackers, while Hungary fans clashed with security personnel before the match.

UEFA fined the Croatian Football Federation (HNS) €100,000 (£77,000/$113,000) earlier this week and warned they could stop tickets being sold to fans who have been identified as hooligans following crowd trouble at the end of their 2-2 draw with the Czech Republic in Lille on June 17. 

All the group matches are completed now and the tournament is due to resume on Saturday (June 25) with the opening three matches in the Round of 16.
