Mounted police had to clear Bristol City fans from the Ashton Gate pitch after violence broke out following the Bristol football derby tonight.
The fans invaded the pitch to celebrate their team's 2-1 over Bristol Rovers in the first round of the Johnstone's Paint Trophy.
Avon and Somerset Police said around a dozen people had been arrested as a result of the disturbances and three officers received medical treatment for non-serious injuries.
As well as trouble after the final whistle there were also disturbances in the stands, and police in riot gear and stewards were needed to keep rival fans apart.
