A 33-year-old man has been convicted of the false imprisonment, assault and sexual assault of two women in separate attacks in Dublin in 2011 and 2015.

The jury will resume deliberating tomorrow on three remaining charges related to another attack on a woman in 2016.

Slawomir Gierlowski, of Galtymore Road, Drimnagh, Dublin, had denied attacking the women on dates in 2011, 2015 and 2016 at locations around Clondalkin.

The prosecution said the attacker used the same modus operandi, targeting women and approaching them from behind using stealth in the early hours of the morning.

Gierlowski pleaded not guilty to nine charges, including false imprisonment, sexual assault and assault.

 This afternoon the jury of 11 men returned unanimous guilty verdicts on six of the nine charges.

The jury will resume deliberating tomorrow on the remaining charges.

During the trial the jury heard evidence from a woman who said that in September 2011 she was attacked from behind as she walked home in Clondalkin.

She said the man began choking her and tried to cover her mouth. He punched her a number of times before pushing her to the ground and sexually assaulting her.

Another woman told the jury that she was attacked in the same area in September 2015.

She said a belt was placed around her neck, duct tape was wrapped around her face and hands and she was knocked to the ground and sexually assaulted.

The prosecution said matching DNA samples were recovered from the victims of both attacks but investigators had nothing against which to compare it.

It was recorded as being from "an unknown male."

On 16 May 2016 another attack took place at Knockmeenagh Lane as a woman made her way through the lane to the Luas stop in the early hours of the morning.

The attacker was armed with a hunting knife.

The woman fought back and grabbed the knife, suffering a serious injury to her hand. The attacker ran off and the woman was helped by people who heard her screams.

Local residents told gardaí they had seen a white van parked in the area. A van was identified on CCTV and gardaí used the PULSE system and linked a similar van to Gierlowski.

They viewed hundreds of hours of CCTV footage and found a van registered to him had been moving in the area in the early hours of the morning of 16 May 2016.

The jury was told that during a search of his house a jacket was recovered on which the victim's blood was found.

The prosecution said his DNA was later linked to this scene and to DNA samples taken from the women in the earlier attacks in 2011 and 2015.

The prosecution alleges that cable ties found near the scene of the 2016 attack were identical to those found in his van.

The court also heard that his fingerprint was also recovered from duct tape found near the scene of that attack. His DNA was also found on a beer bottle found near the scene, according to prosecution lawyers.

Prosecuting counsel Roisin Lacey told the jury that DNA linked the accused to the three crime scenes and that this DNA evidence was quite clear, incontrovertible and uncontested.

She said the DNA was "the cornerstone of the prosecution case, the golden thread that we say runs through each of the crime scenes. It permeates and underpins the case against Mr Gierlowski," she said.

Defence counsel Orla Crowe said there were "inherent frailties in the case."

She urged the jury to use caution when considering the evidence relating to DNA.

"Forensic evidence tells you something is there but it does not tell you when it got there," she said.

She said the victim of the 2016 attack had told gardaí she believed she would be able to identify her attacker but no identity parade was held.

She urged the jury to view the evidence about identifying the van with a serious degree of caution.

Ms Crowe said there was a 29 minute gap in the CCTV footage tracking the movements of the white van.

Other evidence about locating a cigarette packet in the van when it was not visible in photographs was "troubling evidence" she said.

Ms Crowe also said there was no evidence of when the cable ties found in the lane had got there.
