School bully taunts a teenage girl before pulling her to the ground by her hair and unleashing a barrage of punches as her mates egg her on. Footage has emerged of a 15-year-old girl taunting a fellow student before dragging her to the ground by her hair and repeatedly punching her. The two girls, aged 14 and 15, were walking through a car park at Pacific Fair shopping centre on the Gold Coast. Both girls, students at Merrimac State High School in nearby Mermaid Waters, were still wearing their school uniforms.  Vision of the brutal attack shows the moment a 15-year-old grade 10 student, egged on by her friends, approached a 14-year-old in grade nine as she was walking alone. There appeared to be a verbal altercation as one of the girls tried to walk away from the crowd. Daily Mail Australia has been told the girls fell out after a nasty rumour was spread about the younger girl. The older student, wearing tracksuit pants and white sneakers, repeatedly tried to pull her handbag away, while the apparent victim pleaded to be left alone. "Get off me. Let me go," she said before trying to walk away again. But the situation escalated quickly when the 15-year-old, followed by a group of boys including the one filming, trailed behind her. The girl appeared to quickly look back at the crowd, who at this stage were laughing, before chasing the other student down. "Just smack her!" one male voice off camera said. Within an instant, the instigator grabbed the younger girl by the hair from behind and slammed her into the concrete before repeatedly punching her in the head. The instigator grabbed the other girl by the hair from behind and dragged her backwards into the concrete before repeatedly punching her in the head.
