Voting impediment in Tamaya and Imiria elections
During the 1990 elections, PCP-SL stationed itself near Puerto Alegre to prevent Tamaya and Imiria residents from voting in Masisea under threat of death. The Navy responded by bombing the Shining Path checkpoints.
During the 1990 elections, Shining Path supporters stationed themselves on an esplanade near Puerto Alegre to prevent, under threat of death, the inhabitants of Tamaya and Imiria from going to Masisea to vote. This action was part of the PCP-SL's territorial control strategy in the area, which had established Open Popular Committees and Organized Committees in the hamlets of the Tamaya River and Imiria Lake since the end of 1989. In response to this action, helicopters flew over the area and bombed the subversives' main checkpoints. Between March and April 1990, the Navy carried out counter-subversive operations on the Ucayali River to prevent armed actions by PCP-SL during the election process.
