From South Africa, it was revealed that an official investigation to unravel allegations of abuse leveled against officials of the most dangerous prison in the country, has began with government officially taken over the running of the Mangaung prison from the British firm, G4S.

CEOAFRICA.com gathered that inmates claimed they were abused by being subjected to electric shocks and forced injections, even though S4S officials said they have no evidence of abuse by their staffs.

Sources revealed that there is a leaked video filmed inside the high security prison, in which one can hear the click of electrified shields, and shrieking. It also shows a prisoner resisting a medication.

It was further revealed that some of the prisoners do pass out when the shocks became too intense, while many of them complained of broken limbs and other serious injuries.

Speaking to a source, one of the former prisoner said electric shocks were used as torture while sacked security guard said water was thrown over inmates to increase the impact of the charge.

Last week, South African prison authorities claimed to have taken over the running of the prison near Bloemfontein, in the central Free State province after the private security contractors were alleged to have lost control of the facility.
