DOZENS of people have already fallen foul of police action ahead of today's Rotherham United clash against Doncaster Rovers.
South Yorkshire Police has an increased presence in the town centre ahead of the South Yorkshire derby at the New York Stadium.
And almost 80 people have been issued with dispersal orders by police amid concerns about possible trouble.
Police match commander Chief Insp Iain Chorlton said dispersal order powers had been used at a pub "and due to public concern and intimidating behaviour".
He added: “Disappointingly there has already been a need to deal with groups likely to cause antisocial behaviour and crime.
“I apologise for any disruption caused.
“I will not shy away from dealing with groups intending to spoil the event for others.
“Disorder was prevented by targeted and effective police action.
“Dispersal powers are only used when proportionate and necessary to ensure public safety.”
Chief Insp Chorlton said: “Seventy-nine people were dispersed — a large number, but intelligence-led and proportionate to each individual and necessary for public safety.”
