Analysis
On 13 July 2026, while being driven to court, Vusimuzi "Cat" Matlala says he listened as investigators from the Investigating Directorate Against Corruption (Idac) phoned their boss with good news: their witness would sign. That is the account he gave under oath to the Madlanga Commission this week. He says he was only playing along.
Four months later the deal is dead. The three Idac investigators who built it are suspended. The directorate's former head has resigned. And the man the State hoped would help it prosecute senior police officers is using a judicial commission to accuse those same investigators of writing his statement for him.
That is what matters most about Matlala's three days in the witness chair. His claims about ministers and generals got the headlines, but his testimony also shows how South Africa's newest anti-corruption agency handled the most important witness it had.
The deal
At the centre is the Medicare24 contract. A South African Police Service (SAPS) health services tender advertised at about R360 million went to Matlala's company, Medicare24 Tshwane District, in June 2024 for about R228 million. SAPS cancelled it in May 2025 after an internal audit flagged irregularities. By then about R50 million had been paid out. The State alleges that police officers colluded to steer the contract. Suspended National Police Commissioner Fannie Masemola is among the accused. No one has been convicted.
Matlala's testimony, as reported by Daily Maverick, is that he first agreed to plead guilty to seven charges and accept a 15-year sentence with seven years suspended, about eight years in prison. In return he would testify for the State and implicate senior officers. His witness statement was prepared under section 204 of the Criminal Procedure Act, the provision that lets a witness who incriminates himself be discharged from prosecution if he testifies honestly. It was commissioned on 14 June 2026.
Then he walked away. He told the commission that investigators said their superior needed the deal to go through before arresting senior police officers.
A statement changed "three to four times"
Matlala's central claim is that the document carrying his name does not tell his story. He testified that suspended chief investigator Dylan Perumal changed it three or four times and typed in material that did not come from him. He also testified that Perumal and senior investigator Brian Padayachee pressured him to sign. He says Idac shaped the statement to implicate Masemola, KwaZulu-Natal police commissioner Lieutenant General Nhlanhla Mkhwanazi and Crime Intelligence head Lieutenant General Dumisani Khumalo, and that Mkhwanazi was the real target.
These are allegations from a man who faces serious charges of his own and whose account has shifted before. He now disputes several paragraphs of the statement he once accepted, including passages about former police minister Bheki Cele, but he still maintains under oath that he paid Cele cash. Evidence leaders have put contradictions to him between that statement, his testimony to Parliament's ad hoc committee and his evidence now. Cele has previously denied the allegations. Perumal and Padayachee have not yet answered these specific claims at the commission.
The pattern before Matlala
Matlala's claims were not the first of their kind. In July, colleagues of Perumal told the commission that he had fabricated a witness statement and forged a signature in a separate Idac investigation into Crime Intelligence. They submitted voice notes rejecting statements he had allegedly taken in their presence. Justice Minister Mmamoloko Kubayi then suspended Perumal, Padayachee and senior investigator Suneel Bellochun. Bellochun is the official who commissioned Matlala's statement. Idac head Andrea Johnson, who has since resigned, told the commission she knew nothing about the alleged fabrication.
Perumal was taken ill on 6 November and is in hospital, the National Prosecuting Authority (NPA) has confirmed.
So the question is no longer only whether one witness is credible. It is whether evidence gathered by the team at the heart of Idac's most sensitive cases will hold up in court.
What it costs
Losing a section 204 witness is a serious blow. Corruption cases often depend on an insider who can explain what the documents cannot: who asked, who paid, who knew. Without one, the State has to rebuild the Medicare24 case from bank records, procurement files and other witnesses. Lawyers for the accused officers now also have a public record in which the State's intended witness says investigators put words in his mouth.
Idac was supposed to fix exactly this kind of problem. It was made a permanent body inside the NPA in 2024 to bring the cases that commissions and audits had exposed but that rarely reached a conviction. Its credibility is now being tested in the same hearings it was meant to support.
Matlala also faces a separate trial in the Gauteng High Court on 25 charges, including 11 counts of attempted murder. That trial is under way. He and his co-accused have pleaded not guilty, and this article makes no comment on its merits.
The questions left
Matlala's lawyers and the evidence leaders agreed that his most serious claims about Idac and SAPS should go into an affidavit for another forum, citing security concerns. Who will receive that affidavit, and who will test it? Who at Idac approved a strategy that rested on the word of one accused man? And if investigators did shape statements, how many other dockets did they work on?
The commission is due to hand its final report to President Cyril Ramaphosa in January. Until then, the country has an anti-corruption agency whose intended star witness is testifying against its investigators, and a R228 million contract case that has to be rebuilt.
