The 18-year-old went missing in Thebe Locality, Nqobo, on Sunday, said Colonel Mzukisi Fatyela.
“… On Wednesday the community found his private parts in his uncle’s wallet. Police were then called,” he said.
Fatyela said the 42-year-old man took the police to Malande forest, where they found the youth’s mutilated body.
His head, arms and legs had been chopped off and were found not far from his torso.
Earlier police said he would appear in the Nqobo Magistrate’s Court on a murder charge.
Fatyela said he would no longer appear on Thursday, but on Friday.
Human settlements, safety and liaison MEC Helen Sauls-August expressed concern about violent crime in the province.
“It [is] incomprehensible that a human being would commit such a gruesome act to another human being,” she said.
“It’s even worse that a relative could be involved in this inhumane atrocity. Families are supposed to protect each other, instead of butchering each other like this.”
She commended the speedy arrest, the Citizen reports.
