She had only returned home twenty days ago. Suspecting that his wife was having an extramarital affair, the man took a razor blade and slit her neck, police said. The woman, Sabreen, is dead.
The man did the same to his three-year-old daughter Hiba and then also tried to commit suicide, police added.
The accused husband, Javed, who hails from Hapur's Pilkhua, and his daughter are said to be in critical condition and have been admitted to a hospital in Delhi.
The incident was reported from Ghaziabad in Uttar Pradesh.
Sabreen's brother-in-law Aneesh has told police that Javed, who got married during the lockdown, used to beat his wife regularly.
For the past eight months, Sabreen has been living with her in-laws.
