We are appealing for the public’s help in tracing these four men still wanted over violence outside Villa Park when Aston Villa played Legia Warsaw.

Officers contained and dispersed away fans outside the ground before the game, but were subjected to 90 minutes of sustained violence on the evening of 30 November last year.

Dozens of arrests were made, and five officers, two police dogs and two police horses suffered minor injuries.

No home fans were arrested and there were no issues from Aston Villa supporters at any point.

Det Sgt James Birtles, from the team set up to investigate the violence, said: “The disorder that happened that evening was absolutely horrendous.

“We’ve spent hundreds of hours watching CCTV, body worn video and drone footage, and taken hundreds of statements from officers about the violence they faced.

“Since the disorder, we've made three more arrests, in Bristol, Somerset and Leicester. Those men have been bailed while we liaise with the Crown Prosecution Service and seek charges.

“We’re now asking for the public’s help in identifying these four men who we suspect may have been involved in the disorder on the night.

“It’s not clear if they are based in the UK or abroad, and we are continuing to work with law enforcement agencies in Poland and beyond as our work to bring people to justice continues."

If you have information about the identities of these men, get in touch.
