A ninth Rangers supporter has been charged by Police Scotland following racially aggravated offences before last month's Scottish Premiership match against Celtic at Ibrox.
A police investigation was launched after video circulated online of a group chanting sectarian abuse in Glasgow, following the Sunday 29 August fixture.
Police Scotland confirmed on Wednesday that an 18-year-old man had been arrested and charged "in connection with the singing of racist material" in Glasgow ahead of the match.
Three men, aged 24, 21 and 19 years old, were charged a week earlier, with Rangers issuing indefinite bans following the incident, having also condemned all forms of racism, sectarianism and discrimination. A further five men, aged 20, 26, 21, and two 23-year-olds were arrested and charged on Friday.
Rangers said on Thursday: "After liaising with Police Scotland regarding a well-documented incident on Sunday, Rangers have written to three individuals to confirm their indefinite ban from all club fixtures.
"We reiterate our club stance against all forms of discrimination and once again, underline our approach to so-called 'fans' who bring the good name of Rangers FC into disrepute."
Chief superintendent Mark Sutherland, divisional commander for Greater Glasgow Police Division, said following the initial three arrests: "We have made the first of what I expect to be numerous arrests following the disgraceful racial conduct shown by a minority of Rangers supporters who were making their way to Ibrox stadium on Sunday, 29 August.
"Three men, aged 24, 21 and 19 years old, were arrested and charged last night, Wednesday, 1 September, in connection with racially aggravated offences towards a member of the public and for the singing of racist material.
"This racist conduct will not be tolerated and our investigations are continuing. We will continue to work with Rangers FC to identify and take appropriate action against those responsible."
Following the incident in Glasgow, Scottish Cabinet Secretary for Health and Social Care Humza Yousaf tweeted: "For those hurling racist abuse at our Irish community telling them to "go home" - Scotland is their home.
"Disgusted to once again see anti-Irish racism rear its ugly head.
"Solidarity with our Irish community. I am sure Police Scotland will hold those responsible to account."
Show Racism The Red Card Scotland added: "Our charity stands in solidarity with Scotland's Irish and Catholic communities targeted by hate yesterday.
"Chants of "why don't you go home" are racist. Anti-Irish and anti-Catholic hatred in all its forms must be challenged and treated with the seriousness it deserves.
"Religious intolerance and xenophobia must never be accepted as a fact of life by any community or any person in Scotland.
"Educating the future generation to recognise and safely challenge such hate is crucial. Rather than words, communities and charities need more support.
"We commend members of the public for documenting yesterday's scenes and urge all to report them to Police Scotland."
