The âÂÂBig Five cartel" or just the "Big Five" is an alleged criminal syndicate based in Gauteng, South Africa, linked by police to large-scale corruption and violent crime. Crime Intelligence boss LtâÂÂGen. Dumisani Khumalo testified that the cartel âÂÂoperates primarily out of Gautengâ and engages in drug trafficking, hijackings, tender fraud, extortion and contract killings. Its members have cultivated ties with senior politicians, law enforcement officials and business figures to protect their operations. The cartel's existence emerged publicly during the 2025 Madlanga Commission of Inquiry into alleged criminal capture of the justice system.
Public reports have named only a few alleged members or leaders of the Big Five. Crime Intelligence testimony identifies businessman Vusimuzi âÂÂCatâ Matlala and hitman Katiso âÂÂKTâ Molefe as central figures in the syndicate. Matlala, a Pretoria-based tenderpreneur, is described as âÂÂone of the leaders of the âÂÂBig 5â Gauteng-based drug cartelâÂÂ. Witnesses told investigators that the cartel was headed by the late taxi boss Jonathan âÂÂKing Mswaziâ Msibi, whom a detective called the cartel's âÂÂpresidentâÂÂ. Beyond these, Khumalo said the other top members have not been publicly identified, though he hinted they include highâÂÂlevel âÂÂfixersâÂÂ, senior police officers and politicians, who help launder illicit proceeds and thwart prosecutions. Matlala has close ties to businessman Brown Mogotsi, an associate of suspended Police Minister Senzo Mchunu. Matlala remain in custody while Molefe has been released on bail of R400 000.
Investigators say the Big Five runs a diversified criminal enterprise. According to Khumalo and police witnesses, its core activities include drug trafficking and contract killings, supplemented by armed hijackings and kidnappings, extortion, cross-border vehicle theft and rigged government contracts. Matlala himself was linked to an armed hit squad: a detective testified that hitmen âÂÂhad to confirm with Matlalaâ before attempting to kill his ex-girlfriend, actress Tebogo Thobejane. Katiso Molefe is accused of ordering multiple murders (of engineer Armand Swart and DJs âÂÂSumbodyâ and âÂÂVintosâÂÂ) and handling drug shipments.
Khumalo explained that its main âÂÂcommodityâ is drug trafficking, often protected by bribed officials, and that it has âÂÂpenetrated the political sphereâÂÂ. He said the Big Five maintains a national network: though GautengâÂÂbased, it operates âÂÂthroughout the country, including the Western Cape and KwaZulu-NatalâÂÂ. The syndicate is said to cultivate alliances with police, prosecutors and judges to derail investigations: for instance, Khumalo noted that Matlala âÂÂused top police officers and politicians to avoid prosecutionâÂÂ. One witness warned that cartel âÂÂfixersâ (handlers) remain at large even after hitmen are arrested, allowing new killers to be recruited. The Big Five is portrayed as a multiâÂÂsector criminal cartel using wealth and influence to sustain a broad criminal portfolio.
The Big Five's activities are closely tied to political and business networks. Matlala and associates allegedly funded political activities in exchange for favours. Testimony revealed Matlala paid millions to help cover (African National Congress) ANC event expenses, via his associate Brown Mogotsi, and that in return Mchunu's circle helped cancel a police task-team probing cartel cases. Khumalo said the cartel âÂÂbankrolled politiciansâ and placed loyalists in government to shield its interests. One of the examples is Matlala's company Medicare24 won a R360â¯million South African Police Service (SAPS) health-services contract in 2024; the contract was later rescinded amid corruption probes. Matlala gained prominence by securing numerous lucrative government tenders, a phenomenon often termed tenderpreneurship.
HighâÂÂlevel officials have been drawn into the scandal. Former Police Minister Bheki Cele admitted meeting Matlala and even staying at Matlala's Pretoria penthouse in late 2024. Khumalo testified that Matlala was in communications with top police figures, including Hawks head Lesetja Senona and Metro deputy chief Julius Mkhwanazi. Text messages recovered from Matlala showed a âÂÂclear collaboration between Matlala, members of the SAPS, high-level politicians and businesspeople, such as Brown MogotsiâÂÂ. One WhatsApp exchange even involved Lesetja Senona and police minister Senzo Mchunu regarding disbanding the Political Killings Task Team (PKTT).
The Big Five cartel has been the focus of multiple investigations and highâÂÂprofile controversies. The Madlanga Commission (established July 2025) explicitly added the "facilitation of organised crime" to its terms of reference after KhumaloâÂÂs disclosures. KhumaloâÂÂs evidence relies on seized phone records and WhatsApp chats linking Matlala to senior SAPS figures, and was partly heard behind closed doors due to security concerns. Media coverage (News24, TimesLIVE, IOL, Daily Maverick) has amplified the allegations, publishing leaked transcripts and summaries of commission testimony. For example, IOL reported on KhumaloâÂÂs claim that Matlala and Molefe headed the Big Five cartel and outlined their corruption tactics.
On the legal front, Matlala faces a raft of charges. As of late 2025 he is out on remand, charged with attempted murder (of Tebogo Thobejane), money laundering and fraud. A court found the stateâÂÂs case against him âÂÂwater-tightâ when refusing bail. Katiso Molefe is detained on multiple murder charges (Swart, Sumbody, Vintos); his successful highâÂÂcourt bail in October 2025 was described by an investigator as the result of bribery. These cases underscore the cartelâÂÂs intersection with violent crime and the justice system.
