She had called the boy - 13 that month - a "sook" then held on to him as they walked along an Albury street.

"Stop!" he pleaded. "Why are you grabbing my jumper, why are you trying to steal my phone from me? I thought we were friends."

IN OTHER NEWS:

The sustained, humiliating violence the girl and three others - one fronted Albury Children's Court this week - then allegedly inflicted on the boy meant he couldn't recall word-for-word what he said.

But he could remember what was done to him, as he recounted to his mother hours later having somehow escaped his ordeal.

He had, he told his mum, been repeatedly kicked and punched, had duct tape stuck across his mouth, he suffered the humiliation of a girl touching his anus through his pants and had the skin on his arm burnt with a cigarette lighter.

The group allegedly turned violent, a court has heard, when the boy refused to give them his mobile phone PIN. The four girls were arrested soon after and their cases are still progressing through the courts.

One though, the oldest of the accused at 15, will have her matters finalised early next year.

That came with her recent committal for sentence before the District Court in Albury, where she will be arraigned and formally enter her plea of guilty.

"Jade" (not her real name) appeared briefly before magistrate Richard Funston, who on a request from her lawyer ordered the preparation of a Youth Justice NSW background report.

One of the other girls recently secured NSW Supreme Court bail after being denied by Mr Funston, but days later she was back in jail over a breach of her undertaking.

The others aren't in custody, as is a woman facing related charges before the Local Court.

The Lavington girl in court this week will be sentenced on charges of specially aggravated take and detain with intent to obtain advantage, assault occasioning actual bodily harm in company and common assault.

The others have been charged with like offences.

Jade's actions were outlined in an agreed set of Crown facts to ultimately form part of the sentencing bundle to go before the District Court.

The four girls and the victim, this says, attend the same Albury secondary school. The boy was friends with two of them, and the trio would often catch-up outside of school hours.

On the evening of March 18, Jade was at the Albury home where two of the girls, as sisters, lived. They left about 11pm to meet up with the fourth girl.

A couple of hours later, the older sister, aged 12, contacted the victim on the messaging app Snapchat. She arranged to meet him near the Salvation Army church on Corella Street in North Albury.

He agreed, as he hoped to retrieve some items he lent to two of the girls at the house the week before: a cap he gave to Jade and an iPad to the 11-year-old younger sister.

The boy walked to the Salvos, meeting the group in the back car park before they then returned to the sisters' home. Once there, he went into their bedroom with Jade and the fourth girl.

Jade asked him if she borrow his phone so she could login to her own Snapchat account.

He agreed, then left the room and stood just outside in the hallway.

It was then that he got the first clue that something was wrong. The boy could hear Jade and the older sister talking about how they weren't going to return his phone.

She and the younger sister then left the house by climbing out the bedroom window.

He realised Jade still had his phone, but the older sister assured him it would be OK. She would get it back.

The boy left with her and the fourth girl to try to find the other two. They went to the Coles supermarket at Lavington Square, to the church and then finally, Sarvaas Park in North Albury.

He was deeply worried and began to cry; that he would get into trouble with his mum if he turned-up without the phone.

It was then he was scolded by the older sister, who grabbed his jumper so he couldn't run away.

They returned to the house and this same girl made the PIN demand.

But the boy said "no".

"Do it right now or I'll hurt you," it is claimed she said. He refused again.

"All right, let's see how you like it," she said as she grabbed him by his hair, then with the other girl dragged him back to the park.

One - he couldn't remember who - laid down another warning: "Give us the pin right now or I'll hurt you."

When he held his ground, the older sister punched him to the jaw. He relented, slightly, by giving them the PIN, though the wrong number.

ALSO IN COURT:

In retaliation, the facts say, they forced him back to the house, where Jade asked him why he was crying and why he looked depressed.

"(She) just punched me," he said, "because of you." The two other girls and Jade surrounded the boy as the older sister videoed their confrontation on his phone.

The violence then began in earnest.

Jade approached him and kicked him to the stomach. She grabbed him by the shoulders and forced him to the floor, then put her arm around his neck in a choke-hold.

Jade hit him once to the head and several times to the back, then it is claimed the older sister also struck him to the head and shoved his head into the top rail of a bunk bed before grabbing hold of the railing and swinging her legs to kick him to the head, neck and groin.

The fourth girl allegedly did the same.

They applied the duct tape to his wrists and his mouth, making it difficult for him to breath. If he tried to break the tape, he was told, he would "receive 10 punches".

The older sister then, it is claimed, burnt his left arm with the cigarette lighter, but only after her 11-year-old sibling allegedly touched the boy's anus, holding her finger in place for about five seconds.

This pattern of violence continued unabated, with a battery of punches and kicks, including to his neck and groin, until he was able to flee and alert his mother.

It was 4am.
