Six more men have been questioned by police over violence at Rotherham United’s game against Millwall in February.
Their interviews follow six previous arrests, while police have reissued images of nine other men they want to speak to.
A 48-year-old man from Blackpool was interviewed on Monday and five people from London - a man aged 30, two men aged 24 and two 17-year-old boys - were interviewed yesterday, Wednesday.
It follows trouble at the match at the New York Stadium on February 28.
After Rotherham scored in the 85th minute of the game, a number of Millwall supporters attempted to get across into the home supporters’ areas of the ground.
Several stewards were attacked, with riot police deployed to tackle the disorder.
There were further problems between both sets of supporters as fans left the ground.
A number of stewards and police officers suffered minor injuries during the disorder.
Anyone with information about those pictured, or who has information about the incident, is asked to call 101 asking for South Yorkshire Police quoting incident number 290 of February 28, 2015.
