According to K. Jayasree, convenor of the Kadapa Human Rights Forum, there are at least 2,000 labourers from Tamil Nadu in the Kadapa, Chittoor and Nellore and Rajahmundry jails. Woodcutters are usually from Krishnagiri, Vellore, Tiruvannamalai, Dharmapuri and Salem districts of Tamil Nadu. Most of them are from backward communities or denotified tribes. Jawwadimalai, a village in Tiruvannamalai, is famous for its skilled woodcutters. Here, young men even practise carrying logs on their shoulders before being recruited. Many of these hundreds of men in jail, Jayasree says, were picked off buses that were coming from Tamil Nadu and held under preventive detention laws.
