Intelligence watchdog 'lost' truckloads of information related to the Sars 'rogue unit' drama . A trove of intelligence, documents and other datasets handed to the inspector-general of intelligence by the former head of the South African Revenue Service's investigations unit in 2014, and which allegedly proves the extent and scope of the conspiracy against the taxman, has been lost. These datasets, which include a range of documents, recordings, private correspondence and messages, as well as briefing documents, were handed to the then IGI Faith Radebe and her team by Johann van Loggerenberg, then the head of Sars’s High-Risk Investigation Unit on September 29, 2014, after two meetings between the IGI and Sars representatives.
