Extra police officers will be on duty for Sheffield United’s derby with Chesterfield FC on Saturday.
The League One clubs are set to meet Chesterfield’s Proact Stadium on Saturday in front of a sell-out crowd.
Police in Chesterfield and Sheffield have been working with both clubs ahead of the game, which kicks off at 1pm, to maximise the safety of the fans and members of public on the day.
Match day commander, Chief Inspector Brian McKeown, said: “This exciting fixture always attracts a lot of public interest and we are keen to make sure it is a safe and enjoyable occasion for both sets of supporters.
“The majority of supporters will behave impeccably however there is always a very small minority who go out of their way to spoil it for others.
“We are never complacent and we will deploy officers at key locations to prevent and deal with any incidents of disorder on the day. Our approach will be friendly and engaging.
“There will be a significant operation in place both at the ground and other at key locations in the local areas.
“This will include police dogs, trained to detect pyrotechnic flares and drugs so please be responsible and do not attempt to use these on the day.
“We hope supporters will enjoy the match and we ask that they take personal responsibility for their behaviour and drink alcohol responsibly at all times.
“Any person found to be committing any criminal offences will be dealt with fairly and robustly however a football banning order may be sought.”
Anyone with information about the game and any possible planned disorder should call Derbyshire or South Yorkshire Police on 101.
