Detectives investigating trouble at last month's Old Firm match have released CCTV images of ten fans.

Police Scotland launched a probe into alleged disorder, offensive behaviour and vandalism at the match at Celtic Park on September 10.

Last month, a teenager was arrested after blow up dolls were hung from the stands at the game, which finished 5-1 to Celtic.

The 17-year-old boy was detained by police in connection with offensive behaviour and it was the fourth arrest in relation to the blow up dolls and the sixth arrest overall related to the fixture.

Detectives have now released CCTV images of ten men they are tracing as part of their probe and have appealed for any members of the public with information to come forward.

A statement from Police Scotland said: "Officers from Police Scotland are releasing images of people they would like to speak to as part of an ongoing investigation into alleged acts of disorder, offensive behaviour and vandalism during the Scottish Premier League fixture, Celtic v Rangers on September 10.

"Officers are keen to trace the people in the images as they believe they may be able to assist them with their enquiries.
