the plans for the coup d'état were more precise than those of the 23-f previously attempted coup. on october 1, the home office secretary juan josé rosón had knowledge of the conspiracy. after appraising the situation, rosón as well as the president of government leopoldo calvo sotelo and manglano, director of the cesid, decided it was preferable to intervene in a quick way, without more investigations, to avoid a more complicated situation. because of this, on sunday october 2, early in the morning, the three top suspects were arrested. they were artillery colonels luis muñoz gutiérrez and jesús crespo cuspinera, as well as his brother, lieutenant colonel josé crespo cuspinera. at the same time several persons, convicted for the 23-f coup were moved to other prisons, notably the chief of that coup, jaime milans del bosch into algeciras correctional.
