The recent arrest of a former accountant, Mr. Werner Jonker, accused of defrauding his ex-employer of R15 Million highlights the importance of following robust internal checks and following due process when addressing suspected workplace fraud. Jonker appeared at the Boksburg Regional Court today, 20 July, where bail was denied and postponed until 27 July for the purpose of verification of his home and work address.
The arrest follows a forensic investigation conducted by leading forensic investigation firm CS Forensics, which uncovered evidence of alleged fraud, theft, money laundering and cybercrime-related felonies. The investigation revealed a sophisticated scheme involving the falsification of supplier invoices and the sending of company funds into personal accounts over several years.
The matter comes at a time when South African businesses are facing increasingly complex economic crime risks in an ever-growing digital world, with fraudsters exploiting both financial systems and online platforms to mask their crimes.
“This wasn’t Jonker’s first attempt at fraud”, said Christo Snyman,managing partnerat CS Forensics. “We discovered that he allegedly also stole money from his previous employer, and, to recover some of the stolen funds, the employer forcibly repossessed his vehicle which Jonker initially bought for R500 000 cash.” Furthermore, the investigation found that he used a large portion of the funds to fuel his drug and gambling addiction, which Snyman says is an increasingly common behavioral aspect in fraudsters by means of fueling their criminal behavior.

“Fraud inevitably leaves a trial, so organisations need the right controls and investigative processes in order to effectively identify it,” said Snyman. In this case, a thorough evidence-led investigation helped uncover the alleged wrongdoing and provided the foundation for effective law enforcement action. He said that without these processes in place, it ultimately exempts this type of behavior.
The case findings also pointed out suspected violations of the Cybercrimes Act, where emails and WhatsApp messages were supposedly manipulated to create false supplier orders to misappropriate the funds.
Snyman says the case serves as a reminder that organisations should regularly review internal controls, strengthen oversight systems, and act swiftly when suspicious activity is identified, as this employer had done. “As fraud schemes become more sophisticated, businesses cannot afford to rely on trust alone. Prevention, detection, and decisive action remain the most effective defense,” concluded Snyman.
