The allegations of maladministration levied at the Passenger Rail Agency of South Africa has been referred to the state’s special investigating unit by president Ramaphosa.

The ingestigation unit is mandated to probe allegations of improper or unlawful conduct by employees, unlawful appropriation or expenditure of public money, irregular procurement and more, according to a notice published on the government gazette website on Friday. The unit has been asked to investigate Prasa’s activities from at least as far back as 2010.

Thuli Madonsela, the former public protector in a report published in August 2016, said that an investigation into Prasa covering the period from about 2008 to 2013 found the company had a culture of “systemic failure” to comply with its own supply-chain policy.
