Gideon Nieuwoudt (1951–2005) was a former apartheid-era security policeman involved in the torture and murder of several anti-apartheid activists, including Steve Biko. Nieuwoudt, nicknamed "Notorious", was one of the most feared security policemen in the Eastern Cape for his interrogation methods including wet bags, poison, torture machines and often disguised himself as a priest, dubbing him the "Priest from hell". Nieuwoudt had up to five hearings at the Truth and Reconciliation Commission (TRC), in connection with the murders of numerous political activists.
