PUNE: The Central Bureau of Investigation ( CBI ), Pune, on Monday conducted searches at 21 places across Pune and Mumbai in connection with a land-scam case registered by slain RTI activist Satish Shetty . The officials searched offices and residences of an infrastructure company, revenue officials and other individuals.Shetty, who had launched a sustained crusade against alleged usurping of vast tracts of government land in the Maval region by a nexus of revenue officials, private infrastructure firms and other influential people, was hacked to death on January 13, 2010, near his house in Talegaon Dabhade. He had registered the case with the Lonavla city police station in 2009.The Pune rural police crime branch, which had initially investigated the murder, had arrested six suspects and filed a chargesheet against five of them while discharging the sixth suspect. Later, the probe was transferred to the CBI after the high court took suo motu cognizance of the matter. Apart from the five charged, the CBI had investigated six more suspects, including senior officials of an infrastructure firm whose names figured in the land-grab case registered by Shetty on December 15, 2009.In September 2011, the state police filed a closure report in relation to the land grab case and the same was accepted by the court of JMFC in Vadgaon Maval on December 27, 2011.The CBI, in 2013, moved the high court with a plea to reopen the land grab case in a bid to investigate and find crucial links that could lead them to the culprits behind the murder. The high court transferred the land-grab case probe to the CBI on August 8, 2014 and, just two days later, the CBI filed its closure report in the murder case.The CBI, in a statement issued on Monday, said, “The searches were conducted in the offices and residential premises of Deepak Dattatraya Gadgil, authorized signatory of M/s Aryan Infrastructures (a subsidiary of Ideal Road Builders), Virendra Mhaiskar, managing director of IRB Infrastructure, Jyoti Kulkarni, Navin Rai, Siraj Bagwan, Anil Vadgama, Dattatraya Nathu Mandekar, Nawaj Khan, Nasir Mustaq Khan, Ashwini Kshirsagar, Sitabai Taware, Laxmibai Warghade, Ramchandra Balghude, Bapudeo Parkhi, Raghunathdeo Parkhi, Babandeo Parkhi and Chabbudeo Parkhi.”The CBI refused to reveal further details about the searches.Mhaiskar’s cell phone was switched off and was not available for comment.
