Alpha Oumar Barry was imprisoned and was forced to confess to being a plotter of the revolution, as a punishment, he was denied food and water (black diet), and he died on February 26, 1977.
At a press conference on 2 August 1976, Sekou Toure announced the arrest in Conakry of several plotters, including Telli Diallo, Alpha Oumar Barry, Lamine Kouyate and Alioune Drame. After his arrest, the camp commandant Siaka Toure transmitted a series of messages to Alpha Oumar from President Toure demanding that he confess to being a plotter to save the face of the revolution. Eventually Alpha Oumar gave in and made a confession.
