RANGERS have said they will work with police after some of the club's fans were filmed singing an anti-Irish song.
Footage emerged on Sunday of Rangers fans singing The Famine Song on their way to their home game with Celtic.
The song includes the words: "From Ireland they came, brought us nothing but trouble and shame, well the Famine is over, why don't they go home?"
Police Scotland meanwhile said they expect to make arrests and refuted claims they facilitated the fans involved as they marched to the ground.
It comes after several politicians, including Health Secretary Humza Yousaf, condemned the footage and compelled the police to take action.
'Societal issue'
In a statement on their website, Rangers said it condemns all forms of discrimination.
"Following an incident on Sunday, we repeat that Rangers FC condemns all forms of racism, sectarianism and discrimination," read the statement.
"We are working with the police to identify any season ticket holders.
"As a club, we are proud of our Everyone Anyone campaign, led through the Rangers Charity Foundation, our work with a wide range of stakeholders and our on-going dialogue with the Scottish Government.
"Discrimination of all forms is a societal issue within Scotland.
"Those with influence within Scottish discourse should put their energy into eradicating this very serious issue across all sections of Scottish society who suffer sectarianism, discrimination and racism of any form."
'Wholly unacceptable'
Meanwhile Assistant Chief Constable Bernard Higgins of Police Scotland said an investigation had been launched.
"We did not facilitate this event and to say so is inaccurate," said ACC Higgins.
"Officers on patrol came across this group as it was making its way through Glasgow City Centre.
"Due to the numbers and to ensure public and officer safety, additional officers were called to assist and, at this point, individuals' details were noted and the group dispersed.
"A retrospective investigation into this anti-Irish Catholic singing has been launched and we are following up a number of lines of enquiry, including reviewing CCTV footage and footage on social media.
"I fully expect a number of arrests to be made.
"This type of anti-Irish Catholic behaviour is wholly unacceptable. Our enquiries are ongoing to identify those who were involved and we will take the appropriate action against them.
"We would ask anyone who has any information that could assist our investigation to contact us.
"However, the challenges of the sectarianism still evident in some parts of Scotland are a much broader societal problem and, whilst policing will have a role to play in addressing the symptoms, its causes are a problem which require a more effective, joined-up, civic response."
The footage came days after Rangers banned several fans who were recorded singing racist songs about Celtic's Japan international Kyogo Furuhashi.
