An operation between Grampian and Strathclyde police forces led to eight arrests in the north east and one in Fife.
Grampian Police said the majority of the arrests today were in connection with trouble ahead of a Rangers versus Aberdeen match in Glasgow on January 21.
Two police officers were injured in the trouble on Copland Road, next to Ibrox Subway station. A series of arrests had already been made in connection with the incident.
The other two arrests this morning were over city centre violence before Aberdeen’s home match with Celtic last weekend.
Grampian Chief Superintendent Adrian Watson said: “These arrests should send out a clear message to the handful of people intent on using football as a platform to commit acts of violence that behaviour of this type will not be tolerated in any shape or form. They are certainly not the people that the club or city want to be associated with.”
