The bodies of six-year-old Tshiamo Rabanye and five-year-old Mduduzi Nqobizitha Zulu were discovered mutilated last week Thursday, a day after they were reported missing.
Fifty-year-old Nqobile Ndlovu and her 36-year-old partner Mthunzi Mzwakhe Zulu were arrested on Wednesday. It emerged that the former is the grandmother of one of the boys.
