While mayor of Polokwane, Simelane took a loan from a company that brokered a deal between the municipality and VBS Bank.
Several political parties, and civil society organisations, expressed concern about an apparent conflict of interest with the justice minister, who oversees the NPA, being embroiled in the VBS scandal.
President Cyril Ramaphosa has requested a detailed briefing from Justice Minister Thembi Simelane over her involvement in the VBS scandal.
On Monday, News24 and the Daily Maverick reported on a joint investigation, which revealed Simelane had used a "commercial loan" of R575 600 from Gundo Wealth Solutions, owned by Ralliom Razwinane, to purchase a coffee shop in Sandton.
