Two Peruvian human rights groups are demanding a full government investigation into allegations of police torture against protesters in 2005 at a northern mining project, citing photographs of the apparent abuse received from an anonymous source. The photos, published and broadcast widely in Peruvian media, depict police standing over men and women who have plastic trash bags pulled over their heads and hands tied behind their backs. Though their origin is unclear, the images have given new weight to torture allegations by protesters at London-based Monterrico Metals’ Rio Blanco project.
