JOHANNESBURG - The arrest of suspects for the murder of two Soweto boys has come as a shock to the victims' families.

That's because one of those arrested is a 50-year-old relative.

She was taken into custody with her partner, on the same day a memorial service was held, for 5-year-old Nqobizitha Zulu and his 6-year-old cousin Tshiamo Rabanye.

Their mutilated bodies were discovered in White City and Rockville last Thursday, with some of their body parts missing.
