The incident took place on Saturday in Punjab province’s Sahiwal region, when CTD officers had opened fire at a vehicle and killed a man, his wife and their daughter, along with a family friend.

Two minors, who were also in the vehicle, sustained injuries.

“The terrorists fired at the CTD officials following which a shootout ensued. Once the firing stopped, four people were found dead, reportedly as a result of firing by their own accomplices,” a CTD statement had said.

Following the incident, Khan took to Twitter to express his anguish and shock over the incident.

“Still shocked at seeing the traumatised children who saw their parents shot before their eyes. Any parent would be shocked as they would think of their own children in such a traumatic situation. These children will now be fully looked after by the state as its responsibility,” he wrote.

Punjab Chief Minister Sardar Usman Buzdar has ordered the arrests of the officials involved in the shootout.
