Fans from Northern Ireland attending the Scottish Cup quarter-final at Ibrox described chaotic scenes after Celtic defeated Rangers on penalties. Jonathan McAllister from Coleraine, secretary of Sam English Coleraine Rangers Supporters Club, was at the interface between Rangers and Celtic supporters when Celtic fans entered the pitch.

McAllister travelled with a bus of about 50 fans from the Coleraine area, including 10 children such as his daughters River, aged 11, and Natalia, aged 15. He reported Celtic fans throwing beer cans, bottles, and coins at Rangers supporters outside the stadium on Helen Street. He noted only one police officer on a motorbike patrolled the road.

Inside the stadium, McAllister said both sets of fans threw fireworks. He stated Celtic fans charged the pitch after their win, prompting Rangers fans to respond. McAllister viewed the Rangers fans' actions as defensive to protect children from harm.

A member of Banbridge Loyal Rangers Supporters Club, aged in his 30s, attended with about 15 fans. He reported shouting between fans outside before kickoff and Celtic fans jumping on goalposts after the match. He said police sent stewards to control them but they could not.

Both Northern Ireland fans criticised Scottish police for insufficient presence and firmness. McAllister called the lack of protection shocking after 36 years attending matches. The Banbridge fan predicted no future away allocation for Celtic and called for stronger policing in the heated rivalry.

Police Scotland Chief Superintendent Kate Stephen described supporter behaviour as shameful. Officers and stewards faced violence and injuries from individuals with harmful items. A number of arrests were made, with further investigation ongoing alongside Rangers, Celtic, and the Scottish Football Association.

John Swinney, Scottish First Minister, called the violence unacceptable with severe danger to fans, police, and stewards. He backed Police Scotland in pursuing those involved and pledged collaboration with clubs and authorities.
