A 22-year-old man allegedly committed suicide on Thursday after shooting at his girlfriend following an altercation at a guest house, the police said.
The woman, who survived the gunshot, was admitted to a hospital in Delhi where she is battling for life, they said.
The couple, who were studying together at a coaching institute in Ghaziabad, had come to the guest house in Sector 63 where they had booked a room, the police said.
The man, identified as Mohit, hailed from Bulandshahr in Uttar Pradesh and was living in a rented accommodation in Ghaziabad, the officials said.
"The couple had arrived at the guest house in the morning and the incident took place after an altercation between them," a police official said.
The woman was critically injured after Mohit shot at her from a pistol, which was recovered from the spot by the police, the official said, adding that the man later hung himself from the ceiling fan in the room.
"The woman has been referred to Delhi for treatment, while the body of the man was sent for post-mortem," the officer said.
Police are investigating the matter for other details including how the man procured the pistol which was found from the guest house room, he said.
