It was supposed to be the culmination of Millwall’s successful season in League One. The dream would have been promotion – the nightmare was defeat and crowd trouble.
Millwall and Barnsley fans clashed before and during the Wembley play-off final on May 29 with 15 people arrested.
Millwall fans were also filmed inside the ground charging a police barrier to try and get to the Barnsley supporters and the FA pledged they would work with the police to track down the culprits.
Now Met Police have released images of 12 people – supporters of both clubs – wanted for questioning in connection with disorder. Criminal damage was caused to seating at Wembley Stadium and the debris used as missiles.
Millwall Football Club has said anyone identified would be hit with a lifetime ban.
A Millwall FC statement read: “The club deplores the actions of a small minority of its fans during the second half. Such behaviour is unacceptable and anyone found guilty of disorder will face life bans from the football club.”
Anyone with information should call the Metropolitan Police Public Order Branch by dialing 101 or Crimestoppers anonymously on 0800 555 111, quoting the relevant reference number.
