Celtic and Rangers supporters ended up on the Ibrox pitch after Sunday's Old Firm Derby in the Scottish Cup quarter-finals.
An initial pitch invasion by away supporters to celebrate their victory was met by home fans taking to the surface leading to ugly scenes after full time as shown by Premier Sports.
Rangers and Celtic fans clash on Ibrox pitch after Old Firm Derby
Ugly scenes followed Sunday's Scottish Cup quarter-final tie at Ibrox between Old Firm rivals Rangers and Celtic.
After a goalless draw in normal time and extra time, the contest went to a penalty shootout which the visitors prevailed in to progress to the semi-finals.
The tie itself saw Celtic allocated a full stand at Ibrox for the first time in the Old Firm Derby since 2018, with 7,500 Bhoys fans in attendance after years of total away supporter bans and further limitations for clashes between the Glasgow giants.
Headlines post match centred around the scenes after the final whistle, though, as travelling Celtic supporters first took to their rivals' pitch to celebrate their historic cup triumph.
Police were quickly called into further action in separating fans, as the Bhoys contingent was met on the playing surface by Rangers fans, with away players and staff still on the pitch celebrating, while a staff member was on the receiving end of an attack from a home supporter who was quickly apprehended.
The separation did not bring an end to hostilities, with Rangers supporters continuing their position on the pitch having swarmed around the away stand, leading to the throwing of projectiles and pyrotechnics between groups.
Police Scotland have confirmed that several arrests were made after the “shameful behaviour” of supporters, while the Scottish FA have quickly acted to open an investigation into the events at Ibrox.
FGG says: Old Firm derby set for another away supporters ban?
In what was the first Old Firm Derby with a full away allocation allowed, after extensive discussions between clubs and police, hopes for a return to normal in the stands in these fixtures have certainly been dashed by Sunday's scenes.
With no away fans having been permitted in derbies at either stand as recently as 2024, another ban is the likely course of action with the threat of another outbreak, particularly one endangering players and staff, much too big for police and local authorities to allow.
It is not out the question that both clubs face major sanctions themselves too, particularly Rangers in the sense of home fans uncontrollably entering the field of play and threatening and even attacking opposition staff.
