Eleven fans were arrested after violence at the Leeds - Birmingham City match.
Trouble started at the Elland Road ground between away supporters and police and stewards at the end of the game, and continued outside the stadium.
Several match stewards suffered minor injuries.
The disturbance lasted 45 minutes before fans were dispersed. The eleven arrests were mainly for public order offences.
Leeds won the game 1-0 which was in the week the club celebrated it's 100th anniversary.
West Yorkshire Police are appealing for witnesses.
Clearly these were scenes no-one would wish to see and we will be examining CCTV footage and working with both clubs as we investigate what took place.
