MUMBAI (AFP) - A new Bollywood film tackling the thorny issue of caste quotas in Indian government jobs and education is released this week in the face of vocal protests from minorities. Politicians and interest groups championing the low-caste Hindus and other marginalised groups that the system is designed to help have come out in force against Aarakshan. The head of Indias National Commission for Scheduled Castes has even said that director Prakash Jhas film was anti-Dalit and anti-reservation, referring to the community previously known as untouchables. In Mumbai, publicity material was vandalised and more than a dozen activists arrested for protesting outside Jhas office, prompting police to give him and the films actors extra security.
