Unreported World: Carjack City

At least 30 vehicles are carjacked every day in South Africa. The country's cars are routinely fitted with satellite trackers, so that if they're carjacked by thieves an armed response unit can track them. Reporter Marcel Theroux and director James Brabazon visit the country's capital, Pretoria, where this type of crime is acute. They go on patrol with Andries Hlongwane - who works for a private security firm - as he chases the gunmen and recovers stolen cars. It's dangerous work in a private security industry that now accounts for seven per cent of all jobs in South Africa
