Dr Nimesh Desai, head psychiatrist at the Institute of Human Behaviour and Allied Sciences (IHBAS) in Delhi assesses a homeless and mentally unstable man for treatment with an anti-psychotic drug. The effort is part of a unique street clinic project, that sees a representative of the Delhi judiciary give case-by-case legal authority to Dr Desai on the street, to treat the mentally unstable homeless. It is estimated that around 150'000 people - more than one percent of the city - are homeless and the incidence of mental illness amongst this group is very high. Delhi has little formal provision to deal with such a situation.
