Fourteen teenagers have been referred to the Children’s Reporter after fan trouble broke out at a Celtic v Motherwell match in December.
The league game, which saw flares and fireworks set off and dozens of seats damaged at Motherwell’s Fir Park stadium, prompted a number of arrests.
The scenes, which took place at the fixture on December 6, also saw damage caused a green smoke bomb thrown into the Celtic penalty area.
A statement from police said: “Following a police operation in Lanarkshire over the weekend a further 14 people, all males aged between 14 and 16, are the subject of a report to the procurator fiscal.
“They have also been referred to the Children's Reporter in connection with alleged disorder following the Motherwell V Celtic match on Saturday December 6.”
A total of six 16-year-olds, five 15-year-olds and three 14-year-olds were reported to the procurator fiscal as a result of the latest operation.
It takes the total number of people reported to 25.
Celtic Football Club at the time condemned the fans who were responsible for the trouble.
In a statement released after the match, the Parkhead club accused the fans responsible of "tarnishing the great reputation of the club" and promised to keep supporters updated on the investigation into the incident.
A spokesman said: “Clearly we are appalled by the scenes from last night´s match and the actions of a small minority which have again tarnished the great reputation of the club and our supporters on a night when our team produced such a fantastic performance.”
A Police Scotland spokesman added: "During the course of the match, 18 smoke bombs, three fireworks, and one flare were set off. Significant damage was caused to seats within the ground and we are looking into this matter along with the club to establish the circumstances."
The match saw Celtic defeat Motherwell 5-0.
