(From Rettig report) Around January 1975, when the Air Force Intelligence (SIFA) moved out of the AGA center, it transferred the prisoners there to a house in the Apoquindo sector of Santiago, a few blocks from the municipal government offices of Las Condes. This house was used as a secret detention center until March 1975 and was responsible for the agents from the recently created DIFA, which replaced SIFA. After March 1975, the offices of DIFA were moved to Juan Antonio Ríos, No. 6. However, the prisoners from this house were taken to the Anti-Aircraft Artillery Regiment in Colina or to the Cerrillos Hangar.
