Testimony at the Madlanga Commission is set to continue as IPID Assistant Director of Investigations Zelda Maphosho returns to the stand, picking up where a heated session left off over how a major cocaine trafficking investigation was handled. The commission has been diging into the conduct of law enforcement officials linked to one of Gauteng’s largest drug seizures, and Maphosho’s evidence sits at the centre of it.
Her return follows a tense Monday hearing in which commissioners pressed her on the investigation she led into the arrest of three officials. Those officials stand accused of trying to steal narcotics that had already been confiscated by police during the bust.
The matter traces back to a July 2021 operation in Aeroton, south of Johannesburg. Officers stopped a truck and seized 751 kilograms of cocaine, a haul that should have marked a clear win for law enforcement in the province.
Instead, the operation was swiftly clouded by allegations of corruption from within the ranks meant to safeguard the consignment. According to the evidence before the commission, two SAPS officers, a Gauteng traffic officer, and a civilian named Tumelo Nku allegedly tried to gain unlawful access to the seized drugs.
After their arrests, the officers themselves lodged a complaint with the Independent Police Investigative Directorate. That complaint set off the very IPID investigation now facing close scrutiny in front of the commission.
A significant flashpoint came when commission chairperson Justice Mbuyiseli Madlanga questioned how Maphosho’s documentation described Nku. The paperwork refered to him as a police informer, stated plainly as fact, which the chairperson found dificult to accept without verification.
“Why do you call him an informer? Does it mean that you accepted he was an informer, because you are stating it as a fact?” Justice Madlanga asked during proceedings.
Maphosho explained that the label rested entirely on what Nku had told investigators, not on any independent confirmation. She acknowledged the claim was never checked, partly because the supposed handler could no longer be traced.
“I am stating this because that is the information that he gave us. However, the information was not verified because he mentioned a handler as a certain General who had already passed on,” Zelda Maphosho testified.
What the Madlanga Commission Cocaine Trafficking Inquiry Has Heard So Far
The commission was also shown WhatsApp messages exchanged between Nku and Gauteng traffic officer Samuel Mashaba. Those messages allegedly laid out a plan to help the cocaine-laden truck slip past police detection on its route.
To make sense of where things stand, here is how the key figures and claims line up in the mater currently before the commission.
| Party | Role | Allegation or Position |
|———-|————————|
| Zelda Maphosho | IPID Assistant Director of Investigations | Led the probe; described Nku as an informer based on unverified claims |
| Tumelo Nku | Civilian | Allegedly involved in scheme; self-identified as a police informer |
| Samuel Mashaba | Gauteng traffic officer | Allegedly exchanged WhatsApp messages about evading detection |
| Two SAPS officers | Police officials | Accused of attempting to access seized drugs; lodged IPID complaint |
The table shows how tangled the case has become, with the accused officials doubling as complainants and an informer claim resting on testimony that was never independently confirmed.
That detail maters because the credibility of the original IPID investigation hinges partly on how its findings were recorded. Treating an unverified statement as established fact is precisely the kind of gap the commission appears determined to expose.
The broader cocaine trafficking investigation has raised uncomfortable questions about oversight, both of the officials accused of wrongdoing and of the watchdog meant to hold them accountable. When the body investigating misconduct is itself fielding complaints from the accused, the lines blur quickly.
For now, the commission is working methodically through the documentation, the messages, and the sequence of decisions taken after the 2021 seizure. Each thread it pulls sems to surface another question about who knew what, and when.
Proceedings were expected to resume at 9:30am, with commissioners continuing to test the strength of the evidence and the integrity of the investigation that produced it. As the Madlanga Commission preses on, the focus remains squarely on whether the systems built to protect a record-breaking drug haul instead became part of the problem, and what that says about accountability inside South Africa’s law enforcement structures.
