The Green Island police in Hanover are probing a case of grievous bodily harm following an attack at the Green Island High School on Friday that left the school's bursar suffering from extensive injuries.

The alleged attacker is said to be a junior staff member.

The police say the assault was carried out shortly before midday.

One person, who claimed to have been a witness, said the attack was played out in the full view of students and teachers.

The alleged witness said the bursar was talking with the principal while standing in a corridor when the junior staff member assaulted her.

"She grabbed her in her head and start fist har and kick and fling her down on the ground in front of the principal's office," the alleged eyewitness said.

She further said a group of teachers intervened and pulled the attacker off the bursar.

According to the witness, the attacker was then taken away by a vice-principal.

The principal, Ada Mitchell, confirmed that an incident took place at the school on Friday, but declined to reveal details.

Official comment

"The incident has been reported to the Ministry (of Education) but I have not spoken to my chairman yet, so I prefer not to comment officially until have spoken to him," Mitchell said.

This incident follows another at Kingston College last Tuesday when classes had to be suspended at the school's North Street campus after several ninth-grade students attacked and beat a teacher.

The teacher sustained injuries to his eyes.

Two days later, two students from the same institution were taken into police custody for their involvement in another violent incident that left one of their schoolmates injured.
