A man granted bail over claims he sexually assaulted a 13-year-old boy in the front yard of the teenager’s western Sydney home will return to court in December.

Moud Ul Hasan Nuri faced Penrith local court briefly on Thursday on one count of sexual intercourse without consent of the boy, who police say he met via a social application on 28 September.

The 40-year-old’s conditional bail was continued and the case was adjourned to Blacktown local court on 13 December.

Police have alleged the pair chatted, shared images and personal details, and made plans to meet in person.

But when the boy deleted the app that same day, Nuri allegedly went to his home around 6.45pm, approached him in the front yard and pushed him to the ground before sexually assaulting him.

The teen’s mother rushed to help him, prompting Nuri to allegedly run to his vehicle and drive away.

The boy was taken to a children’s hospital for examination.

Nuri was arrested at his Kellyville Ridge home on Sunday and charged later that night.

The case has alarmed police who are warning parents about online safety, especially during the NSW school holidays when children tend to have more access to the internet.

They’re recommending parents monitor the time children spend online, check the family phone bill for unusual outgoing calls, and keep devices in a room accessible by the whole family, rather than a personal bedroom.

“Spend time talking to your child about the dangers associated with online conversations, particularly when communicating with someone that they have only ever met online,” police said in a statement.

Nuri was granted bail, unopposed by police, when he first faced court on Monday. He must report to police three times a week, surrender his passport, provide details about his mobile phone, not contact or go near his alleged victim, and remain 500 metres away from the boy’s suburb.

Nuri sat silent and alone in the court and didn’t speak to media outside.
