John Swinney condemns ‘unacceptable’ Scottish cup final violence

Swinney also criticised the “alarming” use of pyrotechnics during the match at Hampden Park, where two men were arrested.

A 41-year-old was charged with a drug offence and a 30-year-old man was found with a pyrotechnic in his possession.

No arrests have yet been made over the street disorder.

Police Scotland Ch Supt Stevie Dolan said: “Our inquiries are ongoing to identify those who were involved and we will take appropriate action against them.

“I urge anyone who has any information that could assist our investigation to contact us.

“I want to make it clear that the use of weapons and violence will not be tolerated and retrospective inquiries are being carried out.”

Videos shared online showed scared shoppers hiding inside shop doorways, while another showed windows being smashed in a pub full of Celtic supporters.

Ch Supt Dolan added: “We are following a number of lines of investigation, including reviewing CCTV and footage on social media.

“I would like to thank the majority of fans for their conduct throughout the day.”

The match went to extra time and penalties after finishing 3-3, with Celtic emerging victorious after winning the penalty shoot-out 5-4.
