Wanted: Suspects pictured after Villa vs Albion FA Cup trouble
These suspects were wanted by police today over violence which marred Aston Villa's FA Cup clash with West Bromwich Albion.
Trouble flared before and after the game, with two pitch invasions as the game drew to a close.
Seats were ripped up and thrown by Albion fans, while West Brom's Callum McManaman and Boaz Myhill were confronted by dozens of fans as they fled the field.
Rival fans also brawled at the Witton Arms pub ahead of the game, on March 7.
Officers say they are looking for suspects wanted for criminal damage, threatening and intimidating behaviour and entering the pitch.
Police have looking through hundreds of hours of footage from officers who were at the match, as well as that taken by the BBC, the club and Birmingham City Council.
Det Insp Paul Joyce, who is leading the investigation, said: "We already have a huge amount of video footage that officers are trawling through to identify offenders and today we have released 11 images of people we want to identify.
"Some of the behaviour seen on the day of the game was completely unacceptable and our priority is to gather evidence against those who have committed offences and bring them to justice.
"As part of this we are seeking the help of the football community to support our investigation by helping us to collate evidence from photos and videos taken at the match."
Anyone with information should contact police on 101 or call Crimestoppers on 0800 555 111.
