“It was a brief appearance as the matter was not finalised,” Brigadier Thulani Ngubane said.
Eric Ngwenya, Sonwabo Bhani, Mseleki Dalaza and Thabisile Gasa would remain in custody until their next appearance on Friday.
The National Union of Mineworkers’ (NUM) office-bearer was shot eight times in the Nkaneng informal settlement on October 22.
Ngubane said William Setelele, 46, was driving when four men emerged from bushes and shot at his car. He was hit once while he was driving and seven times once he had stopped and got out of the car. He died on the scene.
