A senior police officer told IANS here Ram Kumar was arrested after the inquest proceedings and post mortem report was received on suspicion of having murdered his wife after a domestic quarrel.
"During sustained interrogation the accused broke down and admitted having killed his wife. He claimed his wife would often quarrel with him over petty issues and his drinking habits," the officer said.
On one such occasion, Ram Kumar hit his wife on the head with an agricultural tool and ran away.
"It was only after a few days when a bad smell started coming out of the couple's rented accommodation that the body of the victim was discovered," the official said.
The post mortem report confirmed the victim had died because of a fatal head injury.
"Independent witnesses also told the police the couple would often engage in domestic quarrels," the officer said.
Police have also recovered the agricultural tool which is believed to be the murder weapon.
