Two police officers have been injured during protests outside of Celtic Park earlier this evening following the club's defeat to Ross County in the Scottish League Cup.
Fans gathered outside the stadium in the east end of Glasgow to call for manager Neil Lennon to be sacked in the wake of the team's 2-0 loss.
Police Scotland said two of its officers suffered minor injuries in dealing with the incident, although no arrests have been made.
Justice Minister Humza Yousaf called the scenes outside of Celtic Park "utterly disgraceful".
He tweeted: "Utterly disgraceful scenes outside of Celtic Park from a minority of fans tonight with violence aimed towards Police. Officers have been front & centre keeping us safe during this pandemic, to treat them this way at any time is shameful, to do it during these times is a disgrace".
Superintendent Stevie Dolan, Greater Glasgow division, said: "Around 4.30pm on Sunday, a large number of fans started to gather outside Celtic Park to protest.
"An appropriate policing response was carried out and the group has now dispersed.
"No arrests have been made, however two officers sustained minor injuries as a result of the actions of the gathered group.
"We strongly condemn these actions and remind fans that enforcement options remain at our disposal.
"The Scottish Government regulations are clear that protests are prohibited in areas under Level 4 restrictions and we would urge people to find alternative ways to protest to prevent the spread of coronavirus.
"Disorder of any sort will not be tolerated and appropriate action will be taken where any offences are identified."
