According to police, Virender, who lived in Katri village of Ghatampur area, used to quarrel with his wife Pushpa frequently over financial issues.
Last evening too, they had a spat after which he axed her in a fit of rage.
Later, Virender hanged himself at his house, they said.
The couple also had two children, 2-year-old Sachin and 5-year-old Shivani.
On hearing the children's cries, the neighbours told Virender's brother of the incident, who then informed the police.
