MUMBAI, May 15 -- The Virar police on Thursday arrested Mahesh Patil, the main accused in the murder of Right to Information (RTI) activist Atamaram Patil, while he was planning to flee Maharashtra. Son of quarry owner Bhalchandra Patil who was arrested in connection with the murder case earlier, Mahesh Patil was nabbed from Dahanu, police officers familiar with the matter told HT. According to the police, the revenue department had halted mining operations at several quarries in Shirgaon around four months ago owing to complaints lodged by locals. Yet, the complaints continued, and a complaint about Bhalchandra and Mahesh Patil's quarry was lodged on the chief minister's portal by Patil and Amit Chaudhary, president of the Loktantrik Lok Rajyam Party and a fellow RTI activist, police said. Patil and two revenue officials were attacked on Tuesday afternoon when they were visiting the quarry for site inspection. While Patil was bludgeoned to death, circle officer Prabhakar Patil was grievously injured and is recuperating at a hospital. Speaking to HT, senior inspector Lalu Ture from Virar police station said a long-standing feud between the opposing parties had emerged as a factor in the murder case. "More than half a dozen cases have been registered against Mahesh Patil and his mining activities since 2011. We suspect that the attack was carried out in a fit of rage stemming from this very dispute," Ture said. All angles of the case are being investigated, the officer noted. Vasai tehsildar Deepak Gaikwad said the mine where Patil was killed had been shut earlier due to excessive excavation. "Directives have now been issued to relevant departments to conduct inspections of all mines across the Vasai taluka. Strict legal action will be initiated wherever illegal mining activities are detected," Gaikwad said. According to data from the revenue department, the Vasai tehsil has 38 registered mines spread across areas like Chinchoti, Mandvi, Shirgaon, Kaman, Pelhar, Rajavali, and Tivri. Though 23 among these mines are listed as closed, there have been persistent allegations from local residents regarding continuation of excavation from these mines on illegal basis. "While gelatin and explosives are being used openly in mines, the Vasai tehsildar's office and the Palghar district collector's office have said that they do not have any relevant data, permits or documents," said activist Mackenzie Dabare....
