NEW DELHI/BENGALURU: In a development that puts the Siddaramaiah government in Karnataka in a spot, the CBI probe into the mysterious death of former IAS officer DK Ravi suggests there was a "deliberate diversion" from facts by state officials who planted rumours and false stories about the officer. The agency’s preliminary probe shows that the 35-year-old officer never made 44 calls on March 16 , the day he was found hanging in his southeast Bengaluru flat, as earlier claimed by reports that quoted Karnataka officials. He only made one call as per call records, top sources said."It was alleged that Ravi made 44 calls that day. The reason for such a leak is not known," said a senior officer.The officer’s death was initially described as a suicide, angering several sections of the society, including opposition parties. The state government was accused of indulging in deliberate leaks and the opposition parties demanded a CBI probe into the death. Chief minister Siddaramaiah relented in the face of public outcry and handed over the probe to the central agency.The CBI said on Wednesday it has not drawn any conclusion yet as to whether it was a suicide or not. "The CBI would like to state that all aspects/hypotheses relating to unnatural death of Ravi are being inquired into. The matter is under investigation and conclusion is yet to be drawn in the matter," CBI spokesperson Kanchan Prasad said.The agency sent all forensic evidence — including photographs taken after Ravi's death, his viscera samples and other evidence recovered by Karnataka police — to the Central Forensic Laboratory for detailed analysis.Sources said according to the report of the autopsy conducted by the state government, the death occurred due to hanging, but the agency hasn’t yet concluded whether it was a suicide.They said only the first round of questioning of all persons concerned — including family members, those close to the IAS batchmates, driver and other members of the probe team — has been done while the CFSL report is awaited. It would be difficult to ascertain the cause of death until a detailed forensic report is available, they said.Ravi had been posted as additional commissioner, commercial tax (enforcement) at the time of his death.D K Ravi’s family members trashed reports suggesting the dead officer was involved in realty business. H Hanumantharayappa, Ravi’s father-in-law, denied Ravi was involved in any land deals and had raised Rs 5.4 crore for the same."My daughter, Kusuma, and her friend Hari are in the realty business. They purchased around 50 acres near Doddaballapur for development. Around 15 acres belonged to SC/STs and we are in the process of purchasing it from owners by following the due process of law. Everything is above board and I paid Rs 1.25 crore to Kusuma and Hari for the project. Ravi had requested officials concerned to clear the papers only if they were in order. Beyond this, he was in no way involved in this matter," Hanumantharayappa said.
