Teen Accused Of Violent Assault On Schoolgirl Re-Arrested After Shocking Rant

A 14-year-old girl has been re-arrested over an alleged attack on an Adelaide schoolgirl after a video appeared online where she continued to threaten the victim.

Maddy was allegedly set upon by a group of girls outside an Adelaide McDonald's and violently attacked, while bystanders filmed it on their phones.

Her parents claim Maddy was repeatedly punched and kicked in the head, leaving her with serious facial injuries and missing several teeth.

"It was the worst day of my life," Maddy's mum Courtney told 10 News First.

"I've never experienced anything like that ... it's absolutely shattered me."

Police have charged two girls over the incident, aged 14 and 15.

10 News First understands they attend the same school as the victim in the city's northeast.

A court heard police claim the 15-year-old laughed when she was interviewed about the assault.

It was also claimed the girl was attacked after an allegedly racist comment was posted on Instagram by the victim.

The 15-year-old was remanded in custody ahead of a bail hearing.

Her co-accused was on bail before she was re-arrested on Thursday afternoon.

The re-arrest followed a video being uploaded to social media that allegedly showed the teen making further threats against Maddy.

"Wait until I see her again ... that little s**t is going to get caved-in again," the teen was filmed saying.

Courtney claimed her daughter was still being harassed by her attackers online while she was in hospital.

She also claimed the video of her daughter's assault was sent to her, before being circulated widely around the school community.

"I want them to know that what they do could potentially kill someone," she said.

"That was very, very, very dangerous. That was a very dirty attack."

The Education Department has confirmed it's also investigating the incident and will work with the school to review its bullying policies.
