A retired police sub-inspector allegedly shot himself dead after firing at his son at their home in Uttar Pradesh's Greater Noida over domestic disputes, officials said on Thursday.
The son, around 35, is undergoing treatment at a hospital and his condition is critical, they said.
The incident took place on Wednesday evening in Escort Colony near Railway Road in Dadri area.
"Retired sub-inspector Bachan Singh shot two bullets at his son, hitting him in the chest and a leg and then shot himself in the head using his licensed revolver," Additional Deputy Commissioner of Police, Greater Noida, Vishal Pandey said.
"Bachan Singh died at the spot, while his son was taken to a hospital, where he is undergoing treatment," Mr Pandey said.
The incident took place because of frequent disputes in the family, the officer said, citing an early inquiry of family members and neighbours.
Bachan Singh, around 65, was an alcoholic, and the father-son duo would frequently fight over familial disagreements, and on Wednesday too, they had a heated argument preceding the shootout, according to the officials.
His wife lives elsewhere, while his son is married and his wife stays at the house where the incident took place, the officials said.
