Polish national Robert Boruncinski (33), with an address at Bachelors Walk, Dublin 1, pleaded guilty at the Central Criminal Court to oral rape, aggravated burglary and burglary at an apartment complex on March 5, 2009.
Detective Garda Sheila Sheehan agreed with Aileen Donnelly, prosecuting, that Boruncinski and an accomplice armed themselves with kitchen knives and broke down the door of an apartment where two women were working as escorts.
Holding the women at knife-point, the two men were given €1,300 after they stabbed one of the women in the hand and shoulder blade.
Boruncinski's accomplice claimed that €15,000 was stored in a safe in the apartment and gave the women an ultimatum, telling them that unless they paid him €600 from their earnings each month, they would have to leave Dublin.
Det Gda Sheehan agreed that Boruncinski then told one of the women to accompany him to the bedroom where he orally raped her at knife point.
Det Gda Sheehan agreed that Boruncinski, who was identified by his victim following an ID parade, co-operated with gardai in interview and identified himself on CCTV footage taken from the apartment complex on the day of the robbery.
Hugh Harnett, defending, told the court that Boruncinski was a "hard-working man" who began drinking and fell in with the wrong crowd having been made unemployed at the beginning of the recession.
Mr Justice Paul Carney said that being drunk offered "no mitigation" to one's responsibility to society and afforded no defence to Boruncinski.
Suspending the last three years of a 10-year sentence, Judge Carney said that he took in to account Boruncinski's previous good character, his early guilty plea and the fact that he did not appear to be the "prime mover" in the attack.
