Dynamiting of electrical substation in Santa Rosa, La Oroya

On July 8, 1989, hikers dynamited an electrical substation near the Santa Rosa housing complex in La Oroya. As a direct consequence of this attack, the copper and lead refineries of Centromín Perú were paralyzed. The attack also affected the local electricity supply in the city. This attack was part of a series of actions by the PCP-SL against the mining and electrical infrastructure of the region, which continued during the last months of 1989 with the dynamiting of three electrical towers on July 22.
