BINCI has been accused of participating in a number of other bombings, kidnappings and assassinations against leftists and abuses of guerrilla detainees between the years of 1978 and 1979. In an open letter published on November 29, 1980, by the Mexican newspaper "El Día", five individuals identified as former Colombian military detail a number of activities carried out by BINCI personnel operating as Triple A. Among those implicated in the operations of Triple A are then-Lieutenant Mario Montoya Uribe, who would have participated in the bombing of "Voz Proletaria", and then-Lieutenant Colonel Harold Bedoya, the commander of BINCI who would have given orders to several of the personnel involved.
