I knew sir Sumbal when he was PSO to IGP/Punjab during the tenure of IG Punjab Haji Habib ur Rehman.
Mr. Sumbal was one of the most talented intellectual officer of PSP Cadre. His posting chart till his Shahadat remained as follows upto the extent of my memory and knowledge:-
Former DPO Chiniot Punjab
Former PSO to IGP Punjab
Former DIG Investigation Balochistan
DIG Operation Quetta (embraced martyrdom)

He was transferred from Punjab to Balochistan on the directions of the previous Govt. During his posting in Central Police Office, Punjab, he did many works of welfare for Punjab Police employees. He was kind hearted officer and the loss which has been suffered not only by Police department but also by the nation can never be covered.
May his soul rest in peace.
