KEY POINTS:
Hamilton Girls' High School student Haley Parker, 14, paid a heavy price for hosting a party on Saturday night.
At morning interval on Monday three 15-year-olds set on her in the school corridor.
At least one of the attackers had been booted out of the weekend party.
Haley, a Year 10 pupil, was punched in the face with such force that she banged her head against lockers as she fell to the floor.
While she was on the ground she was kicked in the head, causing blood to splatter about the area.
Police reports that she suffered a broken nose and fractured eye socket are yet to be confirmed, as x-rays taken at Waikato Hospital's emergency department are inconclusive.
But swelling, bruising and cuts to the 14-year-old's head, teeth, lips, eyes, nose and back are all too clear.
She will return to hospital next week for a check-up.
"I was really scared when they were running for me," Haley said as she rested up at home yesterday.
"They had just texted someone to ask where I was. I told Peggy not to say."
From the third storey of a classroom block, Haley looked out a window to see her attackers in the courtyard below enter the building.
At that point she felt intimidated but worse was to come. When confronted she pleaded with the trio.
"I told them it wasn't me telling them to get out of the party."
This was greeted by a punch to Haley's face and having her hair pulled.
"I didn't really feel it [the assault] at the time but I felt it afterwards. All I could hear were noises and all I could see were feet coming at me."
With blood gushing from her face, Haley managed to struggle to her feet and escape down several flights of stairs to the safety of the staff room as her attackers gave chase.
Retaliation appears to be the motivation behind the gang-bashing.
Haley and her mother Wendy Parker said their party was attended by about 150 young people.
At least one of the alleged attackers was there and her behaviour had been "boisterous". After a bedroom door was booted in the girl was ejected from the party and left in tears.
It is believed the girl may have been assaulted herself that night, but not by Haley.
Classmates visited Haley at home yesterday. Emotions ran high as the teenager tried to cover her face, and she worked hard to hold back tears in front of her friends.
Hamilton police area commander Inspector Rob Lindsay said all three attackers had been charged with wounding with intent to injure and would appear in the Youth Court today. "This type of behaviour is totally unacceptable. Parents, caregivers and students themselves have every right to feel safe anywhere in our community," Mr Lindsay said.
School principal Mary Ann Baxter said two of the alleged offenders had been suspended because they had admitted their part in the assault. The third girl had not admitted anything.
Ms Baxter said the school was appalled by the attack. The board of trustees would meet to instigate other disciplinary measures.
Ms Parker said a family group conference would probably be the next step but she held little faith in what it could achieve.
