Three Brazilian women appeared in Limerick District Court where they received suspended prison sentences for running the brothel in the city.
Joiceline Costa Dos Santos (32) and Ana Christina Dos Santos (31) pleaded guilty to assisting in the management of the brothel, while Marcia Da Silva (40) admitted keeping a brothel at the Limerick apartment.
All three also pleaded guilty to obstructing Det Sgt Eamon O'Neill at the brothel in Clancy Strand, Limerick.
There was no mention in court of Quinlivan being the landlord and there is no suggestion that he knew a brothel was being kept at the apartment, which was rented to Da Silva.
Det Sgt O'Neill told Judge Tom O'Donnell that he obtained a search warrant as part of an investigation into the "running of brothels in Limerick city".
Accompanied by officers from Henry Street garda station, the officers broke down the door to gain access.
The three women were found inside. Items seized by gardai included €500, six mobile phones and a laptop computer.
Da Silva admitted she was the tenant and paid rent on a monthly basis to the owner. Da Silva arrived in the country last April to attend a course in Dublin, but only attended one day. The two other women arrived in Ireland last month.
Det Sgt O'Neill said the brothel had been in operation for a number of months. He accepted the women were "pawns" of a bigger operation.
Defence solicitor Ted McCarthy said the three women had families in Brazil to whom they sent money. He said they all had origins in deep poverty. They arrived in the country from Spain and intended to return there.
The three received six-month suspended prison sentences. The judge ordered that they leave the Limerick city area within three days and that the €500 cash be used to get them back to Spain.
Quinlivan (43) is originally from Ballynanty Beg, Limerick. He escaped from Brixton Prison, London on July 7, 1991, with Pearse McAuley from Strabane, Co Tyrone.
The two were awaiting trial on a number of charges arising from an IRA campaign in Britain, including conspiracy to murder former brewery executive Sir Charles Tidbury. Both were arrested in the Republic, in April 1993, on firearms charges. Quinlivan was sentenced to four years in prison, McAuley to seven years.
In December 1997, Quinlivan, who had been described as "an essential cog in the IRA", walked free when the DPP decided not to proceed with a charge of false imprisonment after the alleged victim was unavailable to give evidence.
