On April 27, security guards employed by Tahoe Resources shot and killed peaceful peaceful indigenous protesters against its Escobal silver mine in San Rafael Las Flores, Guatemala. The next day, protesters retaliated by taking 23 police officers hostage. A police raid to free the officers led to a shootout in which one police officer and another protester were killed. Police responded with a series of raids and arrests, and on May 2 the government declared a state of emergency in the region, rendering all protest illegal until further notice.
On May 8, Guatemalan press reported that three Tahoe employees have been detained by police in connection with the April 27 shootings.
The same day, the Network in Solidarity with the People of Guatemala (NISGUA) and MiningWatch Canada sent a letter to Tahoe Resources investors, warning them that growing unrest over the Escobal mine makes the projects a poor investment.
