Two police officers have sustained minor injuries after angry fans gathered at Celtic Park calling for the resignation of Neil Lennon.
On Sunday, Celtic lost 2-0 to Ross County, knocking them out of the League Cup and ending a 35-game winning run for the Glasgow side in domestic cups.
Following the game, supporters gathered outside the football stadium in Glasgow.
More than a dozen police vans were lined up outside the main stand and a police helicopter circled overhead as fans called for Celtic manager Lennon to quit.
Two officers sustained minor injuries during the protests and police condemned the group for gathering in large numbers in a level four area during the coronavirus pandemic.
At her coronavirus briefing on Monday, the First Minister Nicola Sturgeon described anyone who attacks a police officer as “despicable”.
Celtic said in a statement that there was “no excuse” for violent scenes outside the stadium, adding it was “simply unacceptable” that missiles were thrown at players and management.
The club said said: “While we sincerely share the huge disappointment of all Celtic supporters, there can be no excuse for some of the violent scenes at Celtic Park this evening. The Club will be investigating these events fully.
“For players and a management team, who have given so much in recent years and have delivered 11 consecutive trophies, to require an escort from Celtic Park while being targeted with missiles, is simply unacceptable.
“While we understand that only a small number of people were involved in this behaviour, some of the actions this evening, which have obviously left our own players shaken, cannot be condoned in any way.”
Lennon could hear the shouts as he walked into his post-match media conference and said: “It doesn’t make me feel good obviously. We are not in a good moment.
When asked what he would say to supporters outside, Lennon said: “What can I say? That’s their opinion. It’s been rumbling for a while.
“It doesn’t matter what I say or what sort of bravado I put on. It won’t wash. I have to turn it round with results. I can only do that with the players.”
‘Protests are prohibited in areas under level four restrictions and we would urge people to find alternative ways to protest to prevent the spread of coronavirus.’Superintendent Stevie Dolan
Superintendent Stevie Dolan, Greater Glasgow Division said: “Around 4.30pm on Sunday, 29 November, 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 four 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.”
