A 57-year-old cleric in Muzaffarnagar district died after he was castrated by his wife for planning to get married for the third time.
The accused was his second wife and she has been arrested.
The woman told investigators that she pounced upon him with a sharp-edged kitchen knife while he was asleep. She said that she castrated him and he bled to death.
Hazra, the local cleric Wakeel Ahmed's second wife, had earlier pleaded with him not to marry for a third time, but the man had made up his mind.
The incident occurred in Shikarpur village on Friday night and Hazra was arrested on Saturday. His first wife was not at home at the time of the incident.
