In Unión de Reyes, Matanzas, a man has been arrested on charges of "sabotage" by Cuban authorities after he allegedly stole dielectric oil from a transformer at an electrical substation. This case emerges after Matanzas authorities acknowledged in May an uptick in dielectric oil thefts from transformers throughout 2026. In cases involving the theft of dielectric oil and public lighting cables, courts in Ciego de Ávila handed down sentences ranging from seven to 12 years in prison, also in May.
