The Scottish FA have outlined the terms of an independent investigation into the Old Firm fixture at Ibrox last month.

Supporters from both clubs clashed on the park following Celtic’s penalty shoot-out victory over Rangers. The scenes sparked condemnation from Hampden and Holyrood as images and videos from the widespread incident went viral.

Rangers condemned the disorder as ‘unacceptable’ and condemned it ‘unequivocally’ in a strong statement in the aftermath. The club also highlighted the graffiti in the Broomloan Stand that desecrated the memory of the 66 victims of the Ibrox Disaster.

A Rangers spokesman said: “We welcome the appointment of an independent lead and will work constructively with all involved to support a full and fair examination of events leading up to, and including, the game on the 8th of March.”

Rangers stated they would ‘represent the club and our supporters robustly” when cooperating with the authorities and the framework of that investigation has now been revealed by the Hampden hierarchy.

A statement read: “The Scottish FA can confirm the appointment of an Independent Lead and terms of reference for the review into the incidents which occurred at the Scottish Gas Scottish Cup quarter-final between Rangers and Celtic at Ibrox Stadium on 8 March.

“The review will seek to establish the facts surrounding what happened during the day of the match, both within Ibrox Stadium and the surrounding area, including examining events and decisions made in advance of, during and following the match, with a view to identifying lessons learnt and making recommendations to avoid a repeat of similar scenes at other fixtures with a similar risk profile.

“The review will be led by Mark Blackbourne, a vastly experienced sports event consultant who continues to lead on match operations at major club and international competitions under UEFA and FIFA jurisdiction.

“The review process commenced with a meeting of all relevant parties at Barclays Hampden, convened by the Independent Lead, including the respective clubs, Police Scotland and representatives from the Scottish FA.”
