The co-accused are Siboniso Miya, police Sergeant Nandi Nkosi, and Nkanyiso Mafunda.
According to a report in The Citizen, Ncube was murdered in July last year and his body found dumped in Heidelberg.
They all appeared before magistrate Renier Boshoff on charges of conspiring to commit murder. The case was postponed so the State could finalise its investigation.
Ncube’s family attended the hearing and sat silently during proceedings. One of his family members, who did not want to be named, said the family had lost a loving father and breadwinner.
