A police detective known only as Witness A broke down at the Madlanga Commission on Tuesday as he concluded his two-day testimony.
Witness A, a detective investigating criminal cartels, testified at the commission about how his team managed to crack the murder of Vereeniging Engineer, Armand Swart.
This subsequently came at a high cost to him, as this led to him and his colleague, Witness B, being under 24-hour protection.
