Thesis M.A. (Criminology) --Univesity of Limpopo, 2011 / The study on bullying is very important to the effective prevention oflater crime in adulthood. Bullying is one of the anti-social behaviour that may lead to criminal behaviour in adulthood. If bullies are allowed to carry on with this destructive behaviour, when they become adults, they may be involved in criminal behaviour such as partner abuse, road rage, child abuse, theft, etc. When a study is conducted to determine the extent and nature of bullying, the practices of bullying can be prevented on the primary level than waiting for it to continue and try toprevent it in the tertiary level. To prevent this crime at the tertiary level will result in financial losses to the state that will then have to sentence and keep perpetrators in correctional facilities.
