The convicted child abuser brother of Sinn Fein president Gerry Adams claimed 15 years ago he knew of a "very well organised arrangement" of paedophiles.
And he claimed more should be done to investigate paedophile rings.
Liam Adams was convicted earlier this week of raping and sexually assaulting his daughter, Aine Dahlstrom, over a six-year period between 1977 and 1983.
But in an article in the Irish Independent in July 1998 on paedophilia in Co Louth, Liam Adams warned about groups of paedophiles.
The article reads: "Youth community leader Liam Adams says there is a strong local involvement in what he described as a 'very well organised arrangement' which may also have links in Donegal. 'We have names of well-known business people who we are 100pc sure are involved.'
"But he says that the authorities should be doing more to investigate the situation based on the evidence which has emerged so far."
Meanwhile, Gerry Adams has defended his failure to contact the police for nine years about the sexual abuse of his niece.
Gerry Adams was told by Liam in 2000 about the abuse -- but he did not report it to the PSNI until 2009.
Gerry Adams will not face prosecution over claims he withheld information after the Public Prosecution Service (PPS) decided not to launch a case.
