SP Site Sajid Sadozai told that a man named Nadir opened fire inside a house located in Banaras, killing his wife, her sister and brother-in-law, and their son.
He said the incident occurred due to personal resentment within the families.
Police took dead bodies into custody and shifted them to Abbasi Shaheed Hospital for medico-legal formalities.
The suspect fled the scene after shooting and a manhunt is underway for his arrest.
