Bengaluru: The Central Bureau of Investigation (CBI) is likely to rule out foul play in the death of the former Indian Administrative Service (IAS) officer D.K.Ravi.

According to reliable sources, the CBI has examined his autopsy and viscera reports and discussed them with forensic experts at Victoria Hospital, who carried out the officer's post- mortem and is reportedly convinced that it is a case of "suicide." But the agency will probe the circumstances, which may have forced Mr. Ravi to take such an extreme step, said an official source on condition of anonymity.

"The CBI has more or less completed their investigation; examined the material, forensic and circumstantial evidence; the family and the lady officer in question with whom Mr. Ravi was in constant touch and had sent the last message. The investigating team has procured his service files from the Commercial Tax Department, where he last served to find out the alleged threats that he may have faced from the people he is said to have initiated a raid against for tax violations. The CBI will also discuss his official performance with his colleagues and superiors for a clear understanding," said the officer.

Meanwhile, the deceased officer's viscera reports are reportedly clear. "There is no toxic element in his viscera; not even a trace of analgesic or any other drug. If there was an iota of foul play the agency would have requested that his body be exhumed, which happens in most medico-legal cases. The CBI has ruled out exhuming his body," said the source.

The State government had sent the deceased officer's viscera samples to Central Forensic Science Laboratories (CFSL) in Delhi and Hyderabad besides the State Forensic Science Laboratory at Madiwala to establish the cause of his death. "The CBI will once again cross check the forensic analysis of his viscera sample and send it to CFSL, Delhi," the officer added.
