Extra officers for Rangers Pittodrie match
Police Scotland has said extra officers will be on duty for Sunday's match between Aberdeen and Rangers.
A mounted unit and police dogs will also be deployed at the encounter, the first at Pittodrie since Rangers were promoted to the SPL.
About 20,000 fans are expected to see the two rival teams in action.
However, Police Scotland said it would be checking fans for pyrotechnics, such as flares, and would not tolerate sectarianism or violence at the match.
This force is also warning supporters that if they refuse to be searched they will not be allowed into the ground.
Ch Supt Campbell Thomson said: "My warning is clear - any form of anti-social behaviour, whether it involves sectarianism, violence or disorder, is completely unnecessary, completely unwanted and will not be tolerated.
"We will be closely monitoring fans entering the match and will be specifically looking out for anyone in possession of pyrotechnics of any kind.
"It is a condition of entry to the ground that fans allow themselves to be searched and those who refuse will be turned away by the club."
Ch Supt Thomson said anyone who showed up drunk at the gate would also be turned away.
A spokesman for Aberdeen Football Club said: "People will obviously be excited as they are passionate about football and it is up to us to make sure that everyone has the opportunity to enjoy the matchday experience. We are sure they will and we look forward to Rangers return to Pittodrie, and anticipate a great day."
