Three suspects who have been arrested for the killing of two children in Vosman near Witbank in Mpumalanga are expected to appear in the local magistrate court on Wednesday.
One of the children had albinism.
The latest arrest brings to five the number of suspects arrested since the killing of the children in January.
Among the suspects is a traditional healer believed to be from Swaziland.
The traditional healer and another suspect appeared in court on Tuesday and their case was postponed to next Tuesday.
The suspects allegedly kidnapped the two children from their home at gunpoint.
A month later the body of Gabisile Shabane was found buried in a shallow grave while Nkosikhona Ngwenya’s body had to be retrieved from a stream at Emalahleni.
