D. K. Ravi

On 16 March 2015, Ravi was found hanging at his residence in Koramangala, Bangalore. He had gone to office from Nagarbhavi, Bangalore (the house of his in-laws), on Monday morning. He returned to his apartment at St John's Woods near Koramangala by 11.30 a.m. (IST). His family found him hanging by the ceiling fan in his bedroom of their apartment at 6:30 p.m. (IST), when they rushed home after he would not return phone calls made during the day. Following the news reaching the Bangalore police, Police commissioner M. N. Reddi said that forensic and medical evidence hinted the death was prima facie a case of suicide. An autopsy on his body was conducted on the morning of 17 March at Victoria Hospital in Bangalore, following which it was shifted to his in-laws' house in Nagarbhavi. His last rites were performed on 18 March in Bangalore. The eleventh day ritual, in accordance to customs of Hinduism was held in his hometown Doddakoppalu, with his nephew performing the rituals.

On March 17, opposition parties in Karnataka Legislative Assembly demanded from the government an investigation by the Central Bureau of Investigation (CBI), but were refused. They went on to protest the government by launching in assembly, the overnight sit in. The government, however, announced a Crime Investigation Department (CID) investigation the same day. But some critics and members of the public opposed to the investigation by the CID, a police agency under the control of state government, which might risk the investigation's impartiality, efficiency and thoroughness. During initial investigations, the police made references to 44 phone calls made by Ravi to a female Indian Administrative Services batchmate, within an hour, on 16 March, the day he died. However, subsequent CBI Investigation denied this, while revealing that he had called her only once, not 44 times. The Karnataka High Court restrained the government from publishing any interim report of the CID. Yielding to pressure from protests carried out by people across Karnataka and parts of India, and by the opposition parties in the assembly, the state government agreed to hand over the case to the CBI on 23 March 2015.

In April 2015, the union government ordered a CBI probe after the Karnataka government sent a fresh notification without any time limit for the probe. In its report submitted to the Assistant Commissioner, Bengaluru South Sub-Division and Sub-Divisional Magistrate in November 2016, the CBI concluded that Ravi committed "suicide due to personal reasons". On 26 November, it was communicated to the government by the Magistrate to close the case under section 176 of Code of Criminal Procedure, 1973.

Ravi was posted as the Additional Commissioner of Commercial Taxes (Enforcement) by the government on 29 October 2014 in Bangalore. Following this, he prepared a list of top-50 tax defaulters and set a target of ₹ 1,000 crore (US$140 million) tax collection from the tax evading defaulters. He began raids in Bangalore and expanded to places across Karnataka raiding well-known business groups such as Embassy which include shares of state home minister, Rajesh Exports, Shubh Jewellers, RMZ Institution, Nitesh Builders, Prestige Group, Raheja Developers and Mantri Developers, and had reportedly collected over ₹ 138 crore (US$19 million) in the first two weeks. Following this, he allegedly received threat calls from the defaulters.

During his stint as a Deputy commissioner of the Kolar district from August, 2013 to October, 2014, Ravi became almost a public figure due to his functioning as a pro people administrator, and launching of innovative reforms like conducting of Revenue and Podi adalats, which went on to being getting recognized and implemented in other districts by the state government. He also had taken many bold steps to protect encroachment on government lands, including tanks, the main water source in the region and had ensured the checks on quality of building materials of public property like roads, during his tenure at Kolar. Subsequently, he was transferred out of this position in October, 2014, allegedly due to pressure from vested interests involved in land grabbing and illegal sand mining. His popularity among people of Kolar was evidenced when large number of people staged protests, following his transfer orders as deputy commissioner.

Ravi's first posting as a civil servant was as the Assistant commissioner in Gulbarga from August 2011 to December 2012, following which he served as the Deputy commissioner of Kolar district, Karnataka from August 2013 to October 2014. During this tenure, he was known for his work in ridding encroachments and exposing sand mafia in the district.
