Testifying before the Madlanga Commission of Inquiry, Hawks Lieutenant-Colonel Nkoana Joseph Sebola has sharply criticized officers who moved sealed bags from a container into a bakkie during the 9 July 2021 Aeroton cocaine bust in Johannesburg. Sebola told commissioners the scene's integrity was compromised and insisted no officer could identify cocaine by smell alone. He said he only suspected the substance was cocaine after piercing a sealed package with a pin and discovering a shiny powder.
