A man shot dead another man over personal enmity in Karachi's Sharfabad on Sunday afternoon.
The police were present at the site when Sohail opened fire on Munawwar. The men started scuffling because Sohail's wife and three daughters have been staying at 35-year-old Munawwar's house.
Sohail's wife had filed for khula and started living at Munawwar's house. The case has been ongoing in the Sindh High Court for the last three years.
The police brought Sohail to meet his family when he used a 9MM pistol to open fire on Munawwar. Sohail has been taken into custody and shifted to a police station.
The deceased's brother said that the police were working in collusion with the suspect, adding that Munawwar could have been saved if they had acted earlier.
Correction: An earlier version of the story incorrectly stated that the victim Munawwar was 60 years old. The story has been updated to reflect the changes.
