The Ministry of Education has launched an investigation into allegations of bullying at the Mayaro Government Primary School.
Several worrying incidents have occurred at the school which have left one child with a fractured arm and another with injuries to his groin.
Parents have also complained that younger children are being bullied for money and school officials are allegedly turning a blind eye.
The latest incident occurred on May 9, when a Standard One boy was kicked by a Standard Two pupil. That same day, a First Year pupil was injured when another child knocked him off a chair, causing him to fall backwards and hit his head.
The parents have lodged reports at the Mayaro police station and the younger child is expected to undergo an ultrasound on Monday.
The parents are calling for more safety officers and security guards, as well as the creation of a buddy system, where the older children are taught to protect younger ones.
