One eyewitness said: “The university security guard said this had become a regular occurrence and due to him being alone he couldn’t do anything.
“Lots of young people smashing bottles, smoking weed and paying absolutely no attention to social distancing.
“There was also another security guard outside of Sainsbury’s trying to deal with a group. One of them was shouting within centimetres of his face.
"The police eventually turned up but the youths just regrouped elsewhere.”
Police Scotland confirmed they were called at around 9pm on Saturday evening.
The eyewitness added that the video only shows ‘a fraction’ of the number that were there and that there must have been ‘over 100 people gathered’.
They said: “Two parents came and dragged their daughter into a car also shouting at the police for allowing this to happen.”
A Police Scotland spokesperson confirmed: "We were called at around 9pm on Saturday, November 14 following the report of a large gathering in Bristo Square.
"Officers attended and suitable advice was given."
