A Delhi Police sub-inspector allegedly shot dead a 28-year-old woman and then tried to commit suicide by shooting himself at a park in southwest Delhi's Dwarka Sector 4 in broad daylight on 17 January.
The officer, identified as 33-year-old Vijendra Bishnoi - a native of Rajasthan - allegedly had an extra-marital affair with the deceased woman, Nikita, a former news stringer who lived in Dwarka, said a senior police official.
Bishnoi was an accused in a domestic violence case registered on the basis of a complaint filed by his wife in Rajasthan, the official said.
According to police, the incident took place around 9.45 AM when Bishnoi asked the woman to come to the park, where they were last seen sitting on a bench and talking to each other.
Bishnoi reportedly fired three shots at the woman using his service revolver. Before a crowd could gather, Bishnoi pointed the gun towards himself and fired two rounds. While one bullet hit his abdomen, the other hit his chest.
Locals called up the police and the two were rushed to a hospital. The woman was declared brought dead while Bishnoi was reported to be in a critical condition.
He was then moved to AIIMS Trauma Centre where he is fighting for his life.
Bishnoi joined the force as a sub-inspector in 2008 and is presently posted at West Delhi's Ranhoula police station.
He was allegedly involved in an intimate relationship with the woman for the last three years, the senior official said, adding that relatives of both parties have been informed about the incident.
Bishnoi is likely to face dismissal in connection with the incident after he recovers, the official added.
"A case has been registered under relevant sections of law and investigation is underway," Joint Commissioner of Police (southwest) Dependra Pathak said.
