Facing growing food shortages, the government of Salvador Allende placed Bachelet's father in charge of the Food Distribution Office. When General Augusto Pinochet suddenly came to power via the 11 September 1973 coup d'état, Bachelet's father was detained at the Air War Academy on charges of treason. Following months of daily torture at Santiago's Public Prison, he suffered a cardiac arrest that resulted in his death on 12 March 1974. In early January 1975, Bachelet and her mother were detained at their apartment by two DINA agents, who blindfolded them and drove them to Villa Grimaldi, a notorious secret detention center in Santiago, where they were separated and subjected to interrogation and torture.
