In a small faith healing centre in rural Indonesia, Sulaiman chanted in a confused fashion, tugged at a chain attached to his ankle, and shifted restlessly on a hard, wooden bench. The emaciated man has been chained up for the past two years, and is one of thousands of Indonesians with a mental illness currently shackled, according to a Human Rights Watch (HRW) report released Monday. Chaining up the mentally ill has been illegal in Indonesia for nearly 40 years but remains rife across the country, especially in rural areas where health services are limited and belief in evil spirits prevails, according to HRW.
