South Africa G4S prison staff accused of abuse.

Staff at one of South Africa's most dangerous prisons, run by British firm G4S, have been accused of "shocking" abuses and of losing control.

The South African government has temporarily taken over the running of Mangaung prison from G4S and launched an official investigation.

It comes after inmates claimed they had been subjected to electric shocks and forced injections.

The BBC has obtained leaked footage 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.
