The police in Maharashtra arrested 31 Shiv Sena workers, including a legislator, on Thursday for protesting against the proposed Nanar refinery project in the coastal Konkan region’s Ratnagiri district last week, PTI reported.

The MLA, Rajan Salvi, and other workers held a demonstration in Rajapur on April 12. They visited the local police station on Thursday after being served notices for allegedly violating provisions of the Maharashtra Police Act, Inspector Suvarna Patki said. The protestors were produced before a local court, but they were released after they posted bail.

Farmers and fishermen are opposed to the Rs 3-lakh-crore project, which Chief Minister Devendra Fadnavis has claimed will generate employment for residents. The Shiv Sena, which is part of the ruling coalition, has opposed the project, along with the Congress and Raj Thackeray’s Maharashtra Navnirman Sena.

MNS activists vandalised the Mumbai office of a company associated with the project on Monday, a day after their leader declared that the project would not be allowed to go ahead. “Take it wherever you want, take the project to moon, but not in Nanar,” Thackeray had said.

If the project gets completed, it will be the world’s largest single-location oil refinery project, with a capacity to process 60 million tonnes annually, according to News18.
