The administration in Tamil Nadu finally lifted the Section 144, which prohibits assembly of more than 4 people in an area, from Tuticorin.
The section had been imposed after the firing incident in wake of the anti-Sterlite protests.
The lifting of the prohibitory orders indicates that situation was inching back to normal in the region.
The region had witnessed the killing of dozen people in the police firing after protests over environmental concerns.
Violent protests erupted in Tuticorin on May 22 as locals took to the streets demanding the closure of a copper factory of the Vedanta group over pollution concerns.
Over 100 people were arrested for protesting police firing on Tuesday and Wednesday in the port city that left 13 dead.
The Tamil Nadu Pollution Control Board has ordered the closure of the Vedanta Sterlite copper factory after the board found out that the plant had been making preparations to restart production.>
