A bar manager has been convicted of carrying out a sexual assault while three men lay in bed together.
Brian Martin (30) performed a sex act on the victim after they returned to his apartment from an all-night party in Belfast.
Rejecting his claim that it was consensual, a judge told him: "You attacked that man's credibility, you attacked his sexuality and you attacked his honesty."
Martin, of Alfred Street in the city, was released on bail but warned he could be jailed when sentenced next month.
Belfast Magistrate's Court heard how he drove the victim and another man back to his home on August 14 last year.
They talked and drank before all three got into bed together.
Martin, who described himself as bisexual, accepted performing oral sex but claimed the victim was awake the whole time.
It emerged that Martin later sent him an apologetic text.
Martin insisted the apology was not an admission of any wrongdoing but merely in reference to the victim wanting to experiment.
The third man in the bed, who confirmed he is gay, testified to seeing Martin perform the sex act while the victim slept.
Urging an acquittal on the sexual assault, defence barrister Kelly Doherty argued there had been prior sexual contact between the complainant and the third man.
But Judge Chris Holmes decided he was satisfied of Martin's guilt beyond all reasonable doubt.
Sentencing is in four weeks.
