Five people, including an infant, were killed in two separate incidents in Jharkhand, police said on Sunday.
In the first incident at Khilari, 45 km from Ranchi, Bharat Tana Bhagat axed to death his 35-year-old wife and their sons aged 10 and six months on Saturday while they were asleep. A husband-wife fuel reportedly led to the tragedy.
After the murders, Bhagat went to a river and cleaned the axe. He was arrested after villagers informed the police.
In the second incident in Ranchi, Aftab, 35, slit his wife's throat with a razor and later hanged himself. Aftab's relatives told the police that he was unemployed and had been looking for a job.
The couple, who have two sons and a daughter, reportedly fought regularly.
