Johan "Lets" Pretorius (b. 1946) is a medical doctor from Potgietersrus, South Africa as well as a right-winger who belongs to the Boeremag, an irredentist organization. He is married to Minnie Pretorius and has three sons Johan, Kobus and Wilhelm who also belong to the Boeremag.[1]
He was arrested on 15 September 2002 when he was found with a truck laden of weapons and explosives in Lichtenburg. Along with his three sons, he became one of the defendants in the Boeremag treason trial.[2] During cross-examination in this trial, on 26 April 2010 his son Johan claimed that he was not a criminal, but had been a soldier for the "Boerevolk" and thus should be treated as a prisoner of war. Presiding Judge Eben Jordaan rejected this application several months later on 21 August.[3]
