The CBI investigated the case on direction of the Madras High Court and filed report that 108 policemen were guilty in abetting the assault on innocent villagers.
Kodiyankulam Brutality: On 31 August 1995, 600 officials of the Tamil Nadu Police attacked Dalit families in Kodiyankulam village located in the Thoothukudi district. The officials destroyed properties such as televisions, tape recorders, fans, sewing machines, motorcycles, machines, tractors, farm equipment and food grain storages. They burnt the passports of educated Dalit youth in bonfire along with clothes. The only well present in the village was reportedly poisoned by police. They harassed the women and assaulted the elders. Cash and jewellery worth several lakhs of rupees were also taken by the policemen. The police raid was reported to target the material prosperity of the Pallars, on the orders of upper caste officials.
