Armed assailants on Wednesday freed 45 South Africa prisoners awaiting trial, on their way to court hearings.
According to the police, nine of them were later arrested shortly afterwards, while 22 pre-trial detainees were still on the run.
The police said the attack occurred at a location close to the eastern city of Pietermaritzburg.
According to media reports, the five assailants were armed with Ak-47 automatic assault rifles and had attacked a van carrying a total of 45 prisoners.
So far, no one has claimed responsibility for the attack. (dpa)
