A man working with a Union minister allegedly killed himself at his Sarojini Nagar residence in the early hours of Monday, police said.Kundan Kumar, 31, was ‘employed privately’ by Union minister for rural development and panchayati raj Narendra Singh Tomar. He lived with his wife Shivani and a six-month-old son in Laxmibai Nagar in Sarojini Nagar.Romil Baaniya, deputy commissioner of police (south), said no suicide note was recovered from Kumar and the suicide appeared to be a result of domestic issues. Another investigator said that Kumar and his wife were going through a marital discord and lived in separate rooms in the same house.“Kumar returned home around 10pm on Sunday and retired to his room. Around 2am on Monday, his wife wanted to speak to him and knocked on his door, but received no response. When she checked from the balcony window, she found Kumar hanging from the ceiling fan,” said the DCP.She immediately alerted the neighbours and the police after which the door was broken down and Kumar brought down. He was rushed to Safdarjung Hospital where doctors declared him brought dead.The DCP said that a crime team had inspected the death spot and found no evidence of foul play so far. Inquest proceedings are on in the case and the body has been handed over to Kumar’s family after post-mortem, said an officer.An official with the ministry denied the police’s report that Kumar was his personal assistant. “Kumar was a lower divisional clerk who was privately employed by the minister at his office,” said the official, adding that he was not an Indian Government servant. A native of Bihar, Kumar never displayed any anxieties at work and was seen a “jovial” person, said the official.
