The video allegedly shows 16-year-old Brittani Rice pummeling Angela Gardner, while Rice's mother and others watch near a Falls Lake boat ramp on Sunday afternoon.
The attack was allegedly the result of an ongoing feud between the girls that started months ago over a boy.
"This is not a game, this is not a joke," victim's mother Lisa Gardner said. "I'm really speechless it should have never happened."
Lisa Gardner says she is horrified, not only because her 15-year-old daughter was allegedly attacked by a former friend, but because Rice's mother, 33-year-old Tabatha Edwards, reportedly stood by and watched and at times encouraged the vicious attack.
"I can't believe somebody would stand there and let their child do this to anybody and then video tape it," she said. "We had people calling us saying it was on YouTube."
Lisa Gardner also says it was texted around to several people, including her.
She says her daughter was already nursing a broken arm when the attack happened.
"Brittani grabs her by her broke arm, she has a bruise ... a hand print ... where Brittani grabbed her right where the break is," Lisa Gardner said.
She says her daughter was too embarrassed to speak to ABC11 Eyewitness News and didn't want to go to police.
Her mother, an EMT, also says Gardner's broken arm will now take longer to heal and says the attack could have had a tragic ending.
"If Brittani had hit her maybe an inch higher in her temple, she could have killed Angela; she could have killed her instantly," Lisa Gardner said.
She says that is why she is seeking justice for her daughter.
"I want them to pay for what they did to Angela," Lisa Gardner said. "I don't want any other parent or child to go through what I've had to go through the past three days."
Rice is currently charged with assault inflicting serious injury, while her mother is charged with aid and abet and assault inflicting serious injury. Both are out on bond and will appear before a judge in Wake County on October 6.
