Over 250-tribals in Valparai in Coimbatore were on Monday stopped from taking-out a march to the city to press for their long-pending demands, police said. The demands were: provision of rights on forest, patta(deed) for their habitats, land for agriculture and also alternative place in reserved forest-areas. The communities had already discussed the issue with Valparai MLA Kasthuri Vasu and local-district-officials on the issue.
