"He ... kicked him in the head, wouldn't get off him, and the kids had to get him off him."
"I was in shock when I saw my son's face the way it was - his eye was all bashed up and he had a blood nose. I took him to the doctor's and my friend reported it to the police."
The teenager's mother is angry at the way Somerville Intermediate has handled the incident, saying it's taken too long for the main offender to be disciplined.
She said her son was harassed last year by different boys at the school and was assured he would be safe this year.
Instead, she said, it appears he has been regularly harassed again, with things escalating on Friday.
Tracey said the boy who initiated the violence was stood down on Monday but the boy who actually hit her son was not dealt with until Wednesday - something that has left her furious, as her son was too scared to return to Somerville in that time.
"They should have guaranteed that my son was safe to come back to school on Monday and that child wasn't there. They are saying to me that he wasn't there, but other kids are telling me he was."
Principal David Ellery said the school had to speak to both sides as part of its investigation to ensure it had all the facts about what happened.
"There were some serious allegations and potentially some serious consequences so it was important I had the full story."
After being able to speak to Tracey's son in person on Wednesday, Mr Ellery suspended the attacker, whose fate will be decided by the board of trustees.
The other boy, who was stood down for a day, has been allowed to return to Somerville, but with conditions. Mr Ellery said the school took bullying and violence very seriously and had a strong virtues and anti-bullying stance.
Although there was the odd incident - just as at other schools - Mr Ellery said the vast majority of students felt happy and safe at Somerville Intermediate and the school worked hard to ensure things remained that way.
He said the victim returned to school yesterday and appeared to be happy and settled.
He urged any child who felt unhappy or unsafe to talk to staff so the matter could be investigated.
Tracey contacted the Herald about her son's beating after hearing about another case of schoolyard violence. The Herald reported on Monday how a 15-year-old Pukekohe High School student was held down and violated with a vehicle part by three other students.
