Police investigating hooliganism at a football match in Rotherham have identified more than 20 people they want to trace.
Officers have been trawling through about 200 hours of CCTV footage to try to identify all the culprits involved in the disorder at the Rotherham United v Millwall Championship game last month.
Followers of the London side clashed with police officers and stewards as they tried to reach home fans inside Rotherham’s New York Stadium after Millwall fell behind in the 85th minute.
Missiles were hurled at fans and there were further clashes outside.
A police probe into the disorder is under way, but no arrests have yet been made.
Rotherham fans in the stand which Millwall supporters tried to storm spoke of their disgust at the disorder, with children left terrified.
South Yorkshire Police are working with officers from the Metropolitan Police to track down the thugs involved.
Detective Inspector Steve Ashmore, of South Yorkshire Police, said: “Our work continues to identify those individuals involved in the disorder after the game last month.
“Poring through such extensive CCTV footage takes a lot of time and we want to reassure the public in Rotherham that we are working as quickly as we can to progress the investigation.
“At this time, we have highlighted at least 20 individuals from the footage, although we still have more to go through, that we want to identify so we can speak to them about their actions that afternoon.
“This work will be done in partnership with the Metropolitan Police and we are hoping to be in a much stronger position in the coming days, so we can begin targeted arrest attempts.
“We haven’t released these images to the public yet, because we want to have a strong case to present to the Crown Prosecution Service.
“Releasing images too early in an investigation can sometimes have a negative effect and can lessen the chances of securing a conviction.
“We want these people to be brought to justice and don’t want to do anything that could compromise that.
“I urge anyone with information about the disorder to get in touch and tell us what you know.”
