New Delhi, Aug. 21 -- A relationship manager of ICICI bank's Gomti Nagar branch was shot dead on Thursday by her husband, who later killed his sister and then died by suicide, police said. The incident took place at around 12.15pm outside an ICICI Bank branch in Gomti Nagar, where the woman, identified as Divya Mishra, 37, worked as a relationship manager, an officer said. In a WhatsApp status posted before dying by suicide, the accused Manas Mishra alleged that he killed his wife because she had "betrayed" him. The accused was waiting outside the bank in an autorickshaw and the victim was in her car, the officer said. Manas called her outside and shot her before fleeing the spot, he added. HT later learnt that the couple's divorce case proceedings were underway. ADCP (East) Amol Murkut, who reached the bank following the incident, said the woman had worked there for the past three or four years. "The deceased woman's co-workers at the bank identified the attacker as her husband," said the officer. Police said the accused was subsequently traced to the Husaria area, where he allegedly shot his sister, Sheeba Bajpai, before turning the weapon on himself. Lucknow Commissioner of Police Tarun Gauba also reached the crime scene and took stock of the situation. Police said the investigation was underway and forensic teams were examining evidence from the spots linked to the shootings. Pragya, a journalist and YouTuber, also posted on social media that the ICICI Bank employee who was shot was her sister. "I just came to know that my sister has been shot at in Gomtinagar... May God save her," she said in a post tagging the Lucknow police commissionerate and the Uttar Pradesh director general of police. Before the incident, Manas wrote on WhatsApp status that he intended to kill himself and his sister, and alleged that Divya's sister, Pragya, and her husband Bharat Yadav knew everything about the matter. A person running a restaurant rented from the premises where Manas lived told reporters that he saw him rushing into the residence, profusely sweating, apparently after the shooting near the bank. "I even asked him, 'Bhaiya, what's the matter? You appear stressed.' But he told me that it was nothing, just some office issues. Then he went inside," the restaurant owner said. They said the exact sequence of events thereafter was not immediately clear....
