Police investigating disorder at an FA Cup tie between West Bromwich Albion and Wolverhampton Wanderers are trying to trace 25 men.
Trouble flared during the game at the Hawthorns on 28 January which led to play being suspended because of the "completely unacceptable" crowd trouble.
Members of the public and police were assaulted, missiles were thrown and flares were lit, delaying the restart of the game.
Six people arrested at the time have since been released on bail, and now West Midlands Police have released images of other men they would like to speak to.
