Suspended SAPS Sergeant Fannie Nkosi Resigns Ahead of Disciplinary Hearing

A man who once sat in a witness chair and told a commission of inquiry what he knew about senior police officers has now walked out of the police service before it could finish its own case against him. Fannie Nkosi's resignation letter landed on Friday. By Saturday, the South African Police Service had confirmed it had the letter and nothing more.

The disciplinary hearing he was facing, the classification of his departure, the future of the case file — all of it is now a set of open questions the police will not answer.

Suspended SAPS sergeant Fannie Nkosi resigns ahead of disciplinary hearing

Pretoria, South Africa — The police officer who became the Madlanga Commission's Witness F, and then one of its most prominent accused, is no longer a member of the South African Police Service. Nkosi submitted his resignation on Friday, 23 October 2026, IOL reported, citing sources, ahead of an internal disciplinary hearing into alleged misconduct linked to his appearance at the commission. Police spokesperson Athlenda Mathe confirmed on Saturday that the service had received the letter. "We have received the letter of his resignation," Mathe said. That is the extent of what the police have put on the record. Nkosi remains in custody, where he has been since April, and he has not been convicted of anything. Every allegation against him is untested.

The Letter That Ended It

The mechanics are simple and the consequences are not. Nkosi, a sergeant attached to the Gauteng organised crime unit, was suspended in March 2026 after being implicated at the commission, and had been out of operational duty ever since. What his letter says, what it asks for, and what it means for the case against him are not public documents.

Nobody has said whether the hearing survives his departure. eNCA reported that the sergeant had been mulling an exit ahead of the hearing, and that the broadcaster put a question to the SAPS and was still waiting for an answer. That is the shape of the story on Saturday night: a resignation confirmed in one sentence, and a set of institutional questions with no answers attached to them at all.

What the Police Will Not Say

Two questions sit at the centre of this and the SAPS has answered neither. The service has not said whether it classifies Nkosi's departure as a dishonourable discharge. It has not said whether the disciplinary hearing will continue, be postponed or be abandoned. Both matter, because the service has a template and it used it eleven days ago.

In Sibiya's case the wording arrived the same day as the resignation, in a statement published to the service's own account. For Nkosi there has been no statement, no classification and no timetable. A confirmed receipt is not a decision. Until the service says otherwise, the fate of the internal case against him is unknown, and the only process with a date on it is the criminal one.

Eleven Days After Sibiya

Lt-Gen Shadrack Sibiya resigned on 12 October 2026, immediately after his disciplinary proceedings had commenced, and the SAPS described the departure as a dishonourable discharge. Business Day reported that the statement "did not announce a finding on the disciplinary allegations." Acting National Commissioner Lt-Gen Puleng Dimpane explained the mechanics rather than a verdict: "The disciplinary process could not go on.

He resigned immediately. If he resigns immediately, he is no longer our member therefore we are unable to proceed." EWN noted that a dishonourable discharge is generally imposed after a finding of gross misconduct, corruption or serious criminal offences, but may also apply when a member resigns mid-hearing. Sibiya had received three separate disciplinary notices, each dealing with distinct allegations, and he also faces a separate criminal case involving allegations of rape and sexual grooming. None of that has concluded. Eleven days later, Nkosi's letter arrived.

From Witness F to the Accused

The commission's own witness record identifies Nkosi as the man it calls Witness F. He gave evidence over six sitting days from 16 to 23 March 2026, including days of cross-examination. His evidence is the source of the gifts allegation against Sibiya: he told the commission that Sibiya raised no objection to gifts from alleged cartel figure Vusimuzi "Cat" Matlala, including 20 live impala said to have been delivered to Sibiya's farm in March 2024, and that Sibiya pressured him to share a warrant of arrest for the blogger Musa Khawula with Matlala.

Sibiya denies both. Nkosi named taxi operator Madoda "Joe Ferrari" Sibanyoni as one of a "group of five" businessmen; Sibanyoni rejected the allegation. On Day 161, chief evidence leader Advocate Matthew Chaskalson SC led January 2023 WhatsApp material on which Nkosi is named as an alleged party to a plan to buy an IMSI catcher from a supplier in the Czech Republic. He has not answered that allegation before the commission.

The Items in the House

The criminal case against Nkosi rests on what police say they found at his Pretoria North home. IOL reported that firearms, ammunition, police dockets and R52,700 in cash were reportedly recovered during the operation. EWN's timeline records that he was found with seven guns, state-owned ammunition and dockets for serious and violent crimes. eNCA and TimesLIVE reported that a hand grenade was among the items seized.

Inside Politics lists charges of theft, defeating or obstructing the course of justice and the unlawful possession of ammunition and explosives. A search and seizure warrant was executed at the home on 2 April 2026. He was arrested in April 2026 — EWN describes it as his fourth arrest. Bail was refused on 22 April 2026, with the magistrate citing the evidence and public outcry. The High Court dismissed his bail appeal on 3 June 2026. He has remained in custody since.

What He Told the Commission

The commission's witness page carries a caveat that should be read before anything else in this story: "Nothing on this page is a finding. Every allegation he makes about other people and every allegation other people make about him is untested, he has not been convicted of anything, and he and everyone named here are presumed innocent." That applies to the gifts allegation, to the warrant allegation, to the IMSI catcher material and to everything else.

On Days 93 and 94, 20 and 21 April 2026, his WhatsApp exchanges with suspended Tshwane chief financial officer Gareth Mnisi were put to Mnisi under cross-examination. On Day 167, Matlala told the commission that Nkosi collected cash on Sibiya's behalf but refused to name names, saying he did not want to incriminate himself. Nkosi has denied tipping off Matlala about a police raid at his house. IOL reported that Chaskalson alleged Nkosi used a police stamp and his force number on a procurement document.

The Case That Does Not End

There is a second case, in Venda, Limpopo, linked to a November 2022 drug bust in Thohoyandou where police seized dagga, illegal firearms and explosives. Prosecutors allege that months after the bust, Nkosi went to the Thohoyandou police station and falsely presented himself as a colonel sent from SAPS head office, using that claim to obtain the original case docket before returning to remove the confiscated dagga from police custody.

Investigators later discovered that evidence bags containing the drugs had been tampered with. SABC reported in May 2026 that Nkosi allegedly collected a police docket from Thohoyandou under the pretext he was taking it to the SAPS head office in Gauteng. His two criminal cases were combined by the State on 22 July 2026. On 15 October 2026 the matter was postponed to 5 November 2026 for the outcome of representations to the National Prosecuting Authority.

A Service Losing Its Officers

Nkosi is not an isolated exit. Daily Maverick reported that suspended KwaZulu-Natal Hawks head Major-General Lesetja Senona resigned with immediate effect on 26 June after the SAPS rejected a retirement notice he had submitted months earlier, and that his resignation came before disciplinary action could be instituted following Madlanga Commission findings of prima facie evidence warranting a criminal investigation.

Senona was grilled about a R200-million cocaine consignment stolen from a Hawks building in his province in 2021. On 1 July, Dimpane confirmed the dismissal of Brigadier Rachel Matjeng following an internal disciplinary process; Matjeng had come under scrutiny over her relationship with Matlala. Fourteen SAPS members have now been suspended in connection with the R228-million Medicare24 tender, including Lt-Gen Molefe Fani, Lt-Gen Lineo Nkhuoa, Lt-Gen Nonkululeko Edith Mavundla and Maj-Gen Thokozani Mathonsi.

Ian Cameron, who chairs parliament's portfolio committee on police, read Sibiya's timing as evidence in itself: "The resignation on the eve of a disciplinary process points to the fact that he had something to be afraid of."

Six Thousand Cases, No Sanction

The numbers are the argument. Institute for Security Studies analysis found that 6,154 of 7,946 disciplinary cases against SAPS members — 77.4% — ended without sanction. Acting police minister Firoz Cachalia, responding to ActionSA MP Dereleen James, cited the same annual-report and bargaining-council data as showing 6,154 of 7,946 cases, which he put at 74%, resulting in no sanction.

The raw counts agree and the percentages do not, and neither figure is flattering. The ISS notes that presiding officers may be colleagues of those facing charges, and that the system has been widely criticised as weak. Cachalia conceded in May 2026 that how SAPS manages disciplinary matters involving senior managers "had the potential to erode public trust in the criminal justice system." He said: "Discipline and accountability are fundamental to rebuilding public confidence in policing."

What November Fifth Decides

On 5 November 2026 the court hears the outcome of Nkosi's representations to the National Prosecuting Authority. Prosecutor Tholoana Sekhonyana put it on the record: "The matter is on the roll for outcome of representations. The defence needs representations to the Director of Public Prosecutions. The State is requesting that this matter be remanded to the 5th of November 2026 for the outcome of the said representations." Nkosi is seeking a review, reduction or withdrawal of the charges.

He remains behind bars while the court waits. What the SAPS does with his resignation letter, and whether the disciplinary hearing he left behind is formally closed or simply left to rot, is a separate question with no date attached. The commission has published two interim reports, not a final one. The criminal case has not concluded. Nothing here is a finding.
