Malaysian police today arrested 109 members of a group linked to a banned Hindu rights outfit of ethnic Indians. They were arrested for participating in an “illegal” rally in Kuala Lumpur to protest against the introduction of a controversial book in the country's senior school curriculum. The rally was sparked by anger over the government's refusal to drop the school textbook that contains references to the traditional Hindu caste system which the protesters said were racially insensitive to ethnic Indians. The government has set up a panel to look into the complaint and said the book would continue to be used but amendments would be made to several aspects considered sensitive by the Indian community. Ethnic Indians make up less than 10 per cent of Malaysia's 28 million population and have long complained that they are disadvantaged by policies helping majority Muslim Malays.
