The police have arrested Karthik Daulath, a 30-year-old unemployed man, who had approached Haldar as a prospective buyer for a motorcycle that Haldar had put up for sale on an online forum.

The mysterious death of a 35-year-old software engineer from West Bengal in an upscale flat in Bengaluru last week has turned out to be a murder case, according to police.

The body of Sohan Haldar, an engineer working with tech firm ATOS India, was found in his apartment on August 5 by his colleagues after he did not turn up for work for three days. The police initially suspected that he died of natural causes since there was no injury mark on his body. The probe has now revealed that he died of cyanide poisoning.
The police have arrested Karthik Daulath, a 30-year-old unemployed man, who had approached Haldar as a prospective buyer for a motorcycle that Haldar had put up for sale on an online forum.

The police got on the trail of Daulath after it was found that Haldar’s wallet and motorcycle were missing, and his ATM cards were being used to draw money. They examined Haldar’s call records prior to his murder and the CCTV footage from his apartment block. This led the probe team to Daulath, a resident of north Bengaluru and a telecommunications engineering graduate, said DCP (South-East) M B Boralingaiah.

According to the police, Haldar had posted an advertisement on the online forum second-to-none.in on July 27 for the sale of his KTM Duke motorcycle. On August 1, Daulath got in touch with Haldar, saying he wanted to buy the motorcycle.

Daulath allegedly reached Haldar’s flat on August 3 around 2 pm and, after discussing the sale of the bike, the two had a drink. Daulath allegedly mixed cyanide in Haldar’s drink.

After Haldar died, Daulath allegedly took away his wallet, ATM cards and fled with the motorcycle. He found the ATM pin of the cards in Haldar’s wallet and withdrew Rs 27,000 the same day, the police said.

During the investigation, the police found that Daulath called Haldar regularly from August 1 to the day of the murder on August 3. The CCTV footage at the apartment block showed Daulath’s entry on August 3. He was again spotted on CCTV footage of ATM kiosks where he used Haldar’s ATM cards to withdraw money. He was arrested from his home in Rajajinagar.

Daulath was earlier caught red-handed stealing a gold chain from a jewellery shop. He had also attempted to rob a bank in the area, the police said.
