Bullying behaviour no doubt is becoming a common feature, and a nightmare in schools all over the world. It is a worrisome practice in schools because it infringes on the child's right to human dignity, privacy, freedom and security. The physical, emotional and educational consequences of bullying behaviour can never be underestimated. Therefore, this endeavour attempted to further expose us to the meaning, history, extent and nature of bullying behaviour in schools. The characteristics of bullies and their victims and the effects of bullying on the child's mental health were also discussed.
