Mnangagwa served the first year of his sentence in Salisbury Central Prison, followed by Grey Street Prison in Bulawayo and finally Khami Maximum Security Prison in Bulawayo, where he arrived on 13 August 1966 and spent the next six years and eight months. At Khami, Mnangagwa was given the number 841/66 and classified as "D" class, reserved for those considered most dangerous, and was held in a separate block of cells with other political prisoners, whom the government kept away from other prisoners out of fear that they would influence them ideologically. His cell, Cell 42, was in "B" Hall, which also housed future Vice President Kembo Mohadi and revolutionary and journalist Willie Musarurwa.
