IAS officer Anurag Tiwari is seen entering a restaurant in Lucknow with his friend in the last available CCTV footage of him before he was found mysteriously dead hours later on May 17. Four days after the Karnataka cadre officer's death, the Uttar Pradesh police have launched a murder investigation and asked the CBI to take over the case. The officer's parents have alleged that he was under pressure and that he had told them about a threat to his life a few months ago.
