The son of Health Minister Zweli Mkhize has denied that he ever received R3.8 million from communications firm, Digital Vibes.
Digital Vibes received a R150 million tender from the National Department of Health.
The tender was later found to be unlawful. Dedani Mkhize is alleged to have received the cash in the form of a car and money in boxes.
The SIU says in court papers the money must be recuperated and the case be referred to the National Prosecuting Authority.
Dedani Mkhize claims he approached the SIU offering to co-operate with the investigation process but the unit hasn’t contacted him for an interview.
He says he even offered to repay any money if it is proven that he unknowingly benefited from an individual who received funds unlawfully from the state.
Mkhize says he had to hear in the media that the court papers were filed and that neither he nor his lawyers have been served with the court papers.
