More than 20 people were arrested and three cops injured last night amid 'disgraceful behaviour' after thousands of Rangers fans took to Glasgow city centre to celebrate the premiership tile victory.
Police in riot gear were pelted by missiles and flares and came under attack as they tried to clear George Square last night by supporters who refused to move from the central square.
Using special coronavirus powers, cops said the crowd was becoming 'increasingly disorderly' with smoke bombs being let off and they had been confronted with 'violence'.
Fighting was also seen on the streets, with a video showing a man allegedly punched and stamped on Queen Street.
Earlier in the day thousands of Light Blues fans had gathered outside Ibrox as their team roundly beat Aberdeen 4-0 and lifted the Premiership trophy.
Pictures showed fans hanging from the gates and nearby lampposts around the stadium before many took to the city centre.
Scores of supporters were seen letting off flares and waving flags as they made their way from Ibrox to George Square.
Police Scotland earlier revealed that it had turned down the request for the procession from the Rangers stadium to take place.
The huge gatherings came despite warnings from police, senior politicians and club bosses as the coronavirus pandemic continues.
Only Glasgow and Moray will remain at a higher restriction level on Monday amid fears of a spread of the new Indian variant.
Chief Superintendent Mark Sutherland, Police Scotland's Divisional Commander for Greater Glasgow, blasted the scenes last night saying they 'clearly endangered the public'.
He said: "During the evening of Saturday, 15 May 2021, Rangers supporters continued to gather and celebrate the awarding of the league championship trophy in George Square.
"Throughout the day Police Scotland had managed the gathering appropriately tackling anti-social behaviour and encouraging dispersal under Scottish Government Coronavirus regulations.
"As celebrations continued sections of the crowd became increasingly disorderly, property was damaged and people were assaulted.

"Our officers became the focus of the crowd's attention with missiles and flares being thrown at them. Our policing response has been proportionate. We have responded appropriately and consistently to the behaviour of those gathered.
"This disgraceful behaviour which clearly endangered public and officer safety could not be tolerated and officers dressed in full public order equipment and, after appropriate warnings were given, moved in to disperse those present.
"Although most of those present dispersed, a number remained and confronted officers with violence and aggression.
"Missiles were thrown and officers came under direct attack as George Square and the surrounding area was cleared.
"I strongly condemn the behaviour of these supporters who have not only placed our officers at risk but have sought to damage the image and reputation of this great city, especially during this critical period of the pandemic.
"I would like to place on record my thanks to the police and partners who managed this incident, especially those officers who put themselves in danger to bring this violent and disorderly gathering to an end.
"So far we know that three officers have been injured and more than 20 people have been arrested.
"We will be continuing our enquiries and my message is clear that if you have been involved in these ugly scenes then we you will be identified and arrested."
