An 18-year-old man has been charged in connection with sectarian singing at a Rangers match on Saturday.
Grampian Police are also appealing for information after a number of smoke flares were let off by fans at Balmoor as Rangers played against Peterhead.
Goals from Rory McAllister and Scott McLaughlin earned the Blue Toon a point against Rangers in the Division Three season opener.
A Grampian Police spokesman said a report has been submitted to the procurator fiscal and the 18-year-old man is expected to appear in court in due course.
Speaking after the fixture, match commander Allan Ross, said: "The game took place in a generally good natured atmosphere and the overwhelming majority of fans were a credit to themselves and the clubs they support. As is all too often the case however, a very small number of individuals let themselves and their fellow supporters down with their behaviour.
"In addition to the male who was taken into custody in connection with sectarian singing, we are also investigating the use of smoke flares in the away section during the match.
"The use of smoke flares at sporting events is illegal and poses a very real risk to public safety - particularly in a crowded environment like a football match. We are committed to tackling this type of reckless behaviour and the public can be assured that we will take firm action against those who put their fellow supporters at risk in this manner.
"It is important to stress however that the police cannot tackle this issue alone and the continued support of football clubs and the fans themselves is crucial in ensuring we can prevent incidents like this from occurring."
Anyone with any information relating to the use of smoke flares at the match can contact Grampian Police on 0845 600 5700 or Crimestoppers anonymously on 0800 555 111.
