She also announced an additional compensation of Rs 4 lakh to the next of kin of those killed. The government had earlier given Rs 1 lakh to them.
Likewise, those injured in the incident will also get an additional relief of Rs 15,000 apart from the Rs 15,000 they received earlier, an official release said.
The order came after the chief minister accepted the report of the one-member committee headed by retired Justice K Sampath to probe into the incident.
Police resorted to firing in self defence when violence broke out on September 11 after news spread that Dalit leader John Pandian had been detained at Tuticorin en route to Paramakudi in Ramanathapuram district to pay homage on the death anniversary of Dalit leader Imanuel Sekar. In order to maintain law and order, Pandian had been barred from entering Ramanathapuram.
