A Polish roofer who is in prison for random attacks on three women and is being sentenced for trying to rape another woman nine years ago, is still claiming to be innocent, the Central Criminal Court heard today.

Slawomir Gierlowski, 34, from Galtymore Drive, Drimnagh in Dublin, denied being the man who attacked the woman as she made her way home in the early hours of 18 December 2010.

However, DNA found on her clothes was matched to him and a jury unanimously found him guilty.

Judge Michael White today adjourned the case until tomorrow to hear submissions on sentencing after he was told Gierlowski is appealing conviction and sentences in the three previous cases.

Gierlowski was found guilty of attacking and sexually assaulting three women in Dublin in 2011, 2012 and 2015 and is serving 22-and-a-half years in prison.

However, it was only after he was arrested in 2016 that his first attack six years earlier came to light.

The victim had gone in to the courtyard of her apartment block at around 3am on 18 December 2010 when a man followed her in, pushed her to the ground and punched her repeatedly.

He then held her by the throat and choked her, which prevented her from calling out, before sexually assaulting her and trying to rape her.

Gardaí were called and the woman told them her attacker was "super strong" and had a pierced eyebrow.

She said when she whispered "let me go" in Polish his demeanour changed and he became less brutal.

A DNA sample was taken from her clothes but no match was found until June 2016 when Gierlowski was arrested for another such attack.

Gardaí in Clondalkin were investigating a knife point attack on a woman and when they took a DNA sample from him, it matched the sample taken from semen found on the skirt of the 2010 victim.

Two of the other attacks that Gierlowski was convicted of also involved a sexual assault on women walking home after a night out.

He previously used a leather belt, a hunting knife, duct tape and cable ties.

Gierlowski was convicted of all four attacks on four different women after trials by jury.

However, Judge White was told today that he still maintains his innocence of all offences and was appealing the convictions and sentences.

The judge said he wanted to hear submissions on sentencing tomorrow in relation to the possibility of imposing a consecutive sentence in this case and how such a sentence might be affected if Gierlowski's appeals were successful in any of the other cases.
