Evidence that South African special forces murdered top detective shared with BBC

Lt Col Frans Mathipa

Mathipa was no ordinary police officer. He served in The Hawks, South Africa's elite Directorate for Priority Crime Investigation, and was investigating one of the most sensitive cases in the country's recent history when he was killed. Court and police documents reviewed by the BBC suggest his car was trailed by a vehicle registered to a front company for the special forces before he was shot dead on a motorway outside Pretoria in August 2023. According to police sources interviewed by the BBC, Mathipa had told colleagues he feared his investigation could cost him his life just two days before his death. His killing has now become a test case for whether South Africa's military can be held to account by its own civilian courts.

The murder has also exposed a troubling pattern of alleged intimidation. Police documents say special forces issued a warning to The Hawks after Mathipa's death: "You can appoint 10 investigating officers; we will kill all of them," according to the police. Seven special forces members and one military police officer have been charged, all of whom deny the charges. Yet no trial date has been set, and three of the accused have refused to comply with a court order revoking their bail. They remain employed by the army's special forces unit, and one has reportedly been promoted, raising concerns that the prosecution could collapse before it ever reaches court.

Abdella Abadigga

The thread leading to Mathipa's murder runs through an alleged Islamic State operative named Abdella Abadigga, an Ethiopian man who had been granted temporary asylum in South Africa in 2008 before being arrested abroad in 2017. According to Col Tollie Vreugdenburg, the former head of counter-terrorism in The Hawks, South Africa's military and Department of Home Affairs then smuggled Abadigga back into the country on an expired passport and refugee permit to use him as an intelligence asset. He subsequently "went rogue," and community sources in Johannesburg's Ethiopian neighbourhood told the BBC he extorted residents, with US authorities alleging the proceeds funded IS.

Mathipa had been building a case that special forces abducted and killed Abadigga in December 2022, months before Mathipa's own death. The US had sanctioned Abadigga earlier that year as an IS recruiter, fundraiser and trusted supporter of Bilal al-Sudani, a top IS figure in Somalia. Court documents show Abadigga's phone connected to a mast near a military base shortly after his alleged abduction, and was then used to call a number in Somalia. Pentagon did not respond to BBC questions on whether Abadigga's phone helped locate al-Sudani, who was killed by US special forces in Somalia in January 2023, just weeks after the alleged abduction. President Cyril Ramaphosa declined to comment when asked whether Abadigga had been kidnapped at the behest of the US.

Maj Sunnybooi Wambi

One name threads both halves of the case together. Prosecution documents reviewed by the BBC place Maj Sunnybooi Wambi at the scene of the alleged abduction of Abadigga and his bodyguard Kadir Abotese at Johannesburg's Mall of Africa, the very case Mathipa was investigating. CCTV footage seen by the BBC shows a man in a blue top following Abadigga and Abotese as they left the food court and paying for parking three seconds after they did, with the licence plates of the suspected kidnappers' vehicles clearly visible. Police documents also place Wambi in the vehicle that trailed Mathipa just before the detective was shot.

That same tracking data puts the vehicle at the scene of Mathipa's shooting, a piece of forensic evidence that, if sustained in court, would directly tie special forces to the detective's murder. Combined with the alleged warning to The Hawks and the failure of three accused to surrender their bail, the Wambi link crystallises the prosecution's central claim: that this was not a rogue operation but something that flowed from inside South Africa's most secretive military unit. The South African army declined to respond to BBC questions about whether it was responsible for Mathipa's killing, leaving the silence itself as part of the story the prosecution now has to tell.
