In April police in Jaigaon, India, uncovered a human-bones factory and arrested six people. The factory's bones had come from cremation centers on the Ganges River in Varanasi, the Hindu holy city. They were being sold to Buddhist monasteries and to students of traditional medicine. Eastern India was once a flourishing center for the export of human skeletons. The government banned the trade in the late 1980s after human rights groups questioned bone-collection practices. ‘During interrogation [the gang] confessed that the hollow human thigh bones were in great demand in Bhutanese monasteries and were used as blow-horns, and the skulls as vessels to drink from at religious ceremonies,’ investigating officer Ravinder Nalwa told the Reuters news service Tuesday.
