Police Scotland have confirmed that 18 people were arrested following Sunday's Scottish League Cup semi-final between Rangers and Celtic at Hampden Park.
According to BBC Sport, a 27-year-old man was arrested in connection with an alleged sectarian breach of the peace and a 17-year-old man was arrested for allegedly being in possession of a pyrotechnic device.
A further 16 men, aged between 17 and 68 years, were arrested for minor public order offences, with all the arrests made in and around the ground.
The game was settled by Moussa Dembele's late strike, which gave Celtic a 1-0 win over their Old Firm rivals and put them in the final of the competition.
