Honduras' Civic Council of Popular and Indigenous Organizations (COPINH), which called for the demonstration, held President Juan Orlando's government responsible for the crime against Martinez.
The young woman, 26, died in a police unit in La Esperanza city on Sunday. According to a preliminary version of the National Police, she would have committed suicide in the cell in which she was held.
Martinez, who was detained for breaking curfew, was reportedly found tied by the neck to the cell door. As a noose, she used the blouse she was wearing.
