Private investigator Paul O’Sullivan was on Monday night arrested, News24 reported. The arrest reportedly took place at the AfriForum’s offices in Centurion.

O’Sullivan is expected to launch an urgent application at the high court in Pretoria at 9pm for him to be released.

His assistant, Sarah Jane Trent, was on Friday arrested on a charge of impersonating an official from the Independent Police Investigative Directorate and released on R6 000 bail on Sunday evening. It remains unclear what O’Sullivan is charged with.
