A former youth footballer is taking legal action against Celtic FC over historic sexual abuse at Celtic Boys' Club by a former kitman from Northern Ireland and others.
Thompsons Solicitors has lodged papers at the Court of Session on behalf of the client who is seeking damages, with the case to be heard in the months ahead. It said it is a "test case" and there will be more to come.
A number of senior figures at the boys' club, which was not formally affiliated with Celtic FC, have been jailed for sex abuse.
Thompsons Solicitors represents around 25 abuse survivors from the boys' club.
Patrick McGuire, partner with the firm, said beginning formal court action was a "hugely significant" moment for survivors of historic abuse in Scotland.
He said: "One the best-known and celebrated football clubs in the world are now going to be held to account in civil court for decades of the most abhorrent sexual abuse of children.
"These young lads and their families put their complete trust in Celtic and their feeder organisation Celtic Boys' Club. That trust was betrayed over four decades by a succession of paedophiles that operated openly within Celtic."
James McCafferty, a former youth coach who had been living in Lisburn, was jailed for more than six years last May after admitting a string of historic sexual offences against young boys.
Last February, former youth football manager Frank Cairney was jailed for four years after being found guilty of historical sex offences from his time running a church youth team and, later, Celtic Boys' Club.
In November 2018, James Torbett was jailed for six years after being convicted of historical child sex offences.
Torbett - who was involved in setting up Celtic Boys' Club - abused his position of trust to sexually abuse three boys over eight years in the 1980s and 1990s.
Celtic FC did not want to comment on the legal action. In a statement in February, the club said they were dealing with these historical issues in a "responsible manner" but could not discuss any case in any detail amid ongoing legal proceedings.
