The Special Investigating Team probing the suspicious death of Karnataka cadre IAS officer Anurag Tewari reached Bengaluru on Thursday, to probe into affairs at the Food and Civil Supplies Department, where the officer was posted.

The SIT visited two offices of the Karnataka Civil Supplies department including one in the Vikasa Soudha.

The deceased IAS officer’s brother Mayank accompanied the investigating team, while the officers questioned department officials and verified documents, reports said.

Reports also said that the sleuths visited the residence of Anurag as well, and took some documents in Mayank’s presence for the purpose of the investigation.

Anurag was found dead in the early hours of May 17 just outside a Lucknow guesthouse. Anurag was residing there with his batchmate and the Vice Chairman of the Lucknow Development Authority, PN Singh.

PN Singh’s interrogation revealed that Anurag was unhappy with his work and was looking to transfer from the Karnataka to the Uttar Pradesh cadre, investigators said.

The deceased officer had been posted as the Food, Civil Supplies and Consumer Affairs Commissioner of Karnataka at the time of his death, and a furore arose when Karnataka BJP leaders claimed that Anurag was just about expose a massive Rs 2,000 crore scam when he died.

While his family said that he did not speak of a specific Rs 2,000 crore scam, he had told them that there was large-scale corruption in his department.

The post-mortem conducted on his body noted injuries to his lower lip, left cheek and right hand and leg, and concluded that Anurag’s death had not been due to natural causes.

The mystery surrounding his death only grew murkier when an officer investigating the case told the media on Tuesday that the police had received information about Tewari’s death at 5.23am rather than at 6.10am

Three officers, who were on call at the time this first phone call was received, were suspended pending investigation into any charges of laxity against them.
