The Central Bureau of Investigation (CBI) on Friday reached Karnataka's Bidar to investigate the mysterious death of 2007 batch Karnataka cadre IAS officer, Anurag Tiwari.
Anurag was found dead in mysterious conditions outside a VIP guest house in Uttar Pradesh's Lucknow last year.
The post-mortem report had said the cause of death was "asphyxia".
Earlier, Tiwari's murder case was transferred to the CBI after his family members demanded a CBI probe.
They had also registered an FIR with the police in Lucknow against unknown persons under the section 302 of the Indian Penal Code (IPC)
"In the complaint, it was alleged that Anurag Tiwari was under pressure as he was about to uncover a scandal. Hence, we filed the case under the IPC 302. We have also forwarded their demand for a CBI investigation," Lucknow Senior Superintendent of Police (SSP) Deepak Kumar told ANI.
