A woman has described feeling “disgusted” after allegedly being sexually assaulted during the early hours of the morning.

Giving evidence on the fourth day of a Royal Court trial, the woman – the fourth to accuse Abdelkarim Arfaoui of sexually assaulting her – said that the defendant had persistently propositioned her for sex despite repeatedly being told to leave her alone.

Mr Arfaoui denies ten offences he is accused of committing against five different women. The most serious allegation he faces is of attempted rape.

The fourth woman, who said she was attacked by Mr Arfaoui, appeared in court this morning and gave an emotional account of her encounter with him.

She said he appeared drunk and was “unsteady” when he approached her, and that when he greeted her, she replied because she was “a polite person”. The court was told she gave him a fake name and he replied with vulgarities about his penis.

“I asked him to stop with that kind of conversation,” the woman said.

The woman recalled telling him: “Leave me alone and go home,” adding that she felt “nervous” about his presence.

She stopped outside a shop and Mr Arfaoui apologised and went to shake her hand, she said – but she replied: “Don’t touch me. Leave me alone and go away.”

However, the woman told the court that Mr Arfaoui continued to pursue her and told her that he would have sex with her.

“When I was going to cross the road, he was behind me and grabbed my butt cheek,” she said. “I took my phone out of my pocket and said I was going to call the police.”

She added that she did not immediately call the police because she was shocked and lost, but reported the incident later when she saw an appeal on Facebook.

Crown Advocate Lauren Hallam, prosecuting, asked: “How did this incident make you feel?”

The woman said: “Disgusted. Dirty. Lost.”

Jurors were shown several CCTV clips where the woman and Mr Arfaoui are seen walking down the street.

Advocate Greg Herold-Howes, defending, put Mr Arfaoui’s account to her, stating his client accepted he had approached her, introduced himself and went to shake her hand. But, he said, Mr Arfaoui “says he was trying to obtain directions because he had become lost”.

The woman said: “Absolutely not.”

“You don’t agree with that?” the advocate said.

The woman said: “No, no, no, no. I told him ‘don’t touch me, leave me alone, go home’.”

“He says he immediately did so and left you,” the advocate said. “He says he never intentionally touched you sexually.”

The woman said: “That’s a lie.”

The trial continues. Commissioner Alan Binnington is presiding.
