“To say I’m utterly disgusted by the Rangers fans who rampaged through the city would be an understatement,” Sturgeon tweeted on Sunday. “In normal times, the violence & vandalism, & the vile anti Catholic prejudice that was on display, would have been utterly unacceptable. But mid-pandemic, in a city with cases on the rise, it was also selfish beyond belief.”

Rangers lifted the Scottish Premiership trophy on Saturday after defeating Aberdeen 4-0 at home in Ibrox. Rangers went the season unbeaten, and their victory was a given since March. Still, having lost out every year since 2011 to rivals Celtic, the win was a decade in the making, and Rangers’ die-hard fans celebrated accordingly.

Thousands marched from Ibrox toward George Square in the center of Glasgow after the win. Scotland’s coronavirus restrictions clearly prohibit such large gatherings, and police earlier urged supporters “not to gather and to take personal responsibility for their actions.”

The warnings fell on deaf ears, and an estimated 15,000 fans packed into George Square. They cheered and chanted for hours, and violence followed, in the words of Assistant Chief Constable Gary Ritchie, “as the effects of alcohol took hold.”

Police attempted to disperse the crowd, and were pelted with missiles and flares. Fights between fans, and between fans and police, broke out. Some graphic scenes of street violence were caught on camera. In one particularly grizzly incident, a man was repeatedly kicked in the head on Queen Street, around the corner from George Square.
