A number of Adivasis and forest dwellers from across the country staged a protest at Jantar Mantar here on Friday to demand an end to grabbing of forest land for the benefit of Central and State governments and private companies. Joined by leaders of the CPI(M), CPI, CPI(ML) Liberation and Gondwana Ganatantrak Party, the protesters tried to march towards Parliament but were detained by the police. The protesters charged the Central and State governments with violating the law and people's rights in order to keep their control over forests and forest lands.
