Piet Brink was shot at on Sunday at the exact location where Wandile Bozwana and another employee were gunned down last Friday.

Police allegedly failed to open a criminal case after Brink escaped what appears to be an attempted hit.
EWN reporter Barry Bateman said the matter had been escalated to the provincial detective's office, along with Bozwana's case.
