A 15-year-old girl has been stabbed in the head by another teenage girl at a school.
The girl was attacked with a "sharp implement" believed to be a pair of scissors, police said.
The stabbing happened as the girl queued for lunch in the canteen of Collingwood College in Camberley, Surrey.
Natasha Jackman was stabbed in the eye, head, back and chest her father Humperdink said.
He told BBC Radio Five Live that the gang approached Natasha and said: "We are going to give you a haircut or we are going to set your hair on fire."
When she stood up to the fellow pupils she was stabbed with what appeared to be a pair of scissors, Mr Jackman said.
He added: "According to Natasha there was only one teacher in the area and they were trying to deal with a fight elsewhere in the cafeteria."
The victim was taken to Frimley Park Hospital with serious injuries.
A spokesman for Surrey Police said the girl's injuries are not life-threatening and she is not receiving intensive care treatment.
He added: "A 15-year-old girl was arrested and taken to Woking police station for questioning."
It is understood the suspect is a fellow pupil at Collingwood College.
The school described the incident as an "isolated case".
