Police in Nottinghamshire are investigating tonight after a secondary school pupil stabbed a number of students with what's believed to be an insulin needle.
Several children have had to go to hospital to be tested for infections including hepatitis and HIV.
Some parents have accused the school of failing to take the attack seriously enough.
But the head-teacher John Tomasevic has told Central Tonight he is happy with the school's response.
The attack happened during the lunch break at Toot Hill School in Bingham in Nottinghamshire.
Today three of the victims told how they were stabbed in the head and neck, it appears a fourteen year old boy attacked pupils at random with a diabetic pen.
It's thought as many as 20 pupils may have been caught up in the attack.
The school advised parents whose children were hurt to go to hospital for checks.
Nine have already been tested for infections such as Hepatitis and HIV, health officials say the risks are very slim, but the test results won't be known for three months.
Elena Georgiou's son was one of those stabbed. She says she only heard about it from another parent.
The school says the pupil who attacked fellow students has been suspended for five days while they carry out an internal investigation.
Nottinghamshire Police say they are currently working with the school:
