According to the Counter-Terrorism Department official Raja Umar Khattab, Sabeen Mahmud’s driver Ghulam Abbas was a key witness in the prominent activist’s murder.
Ghulam Abbas worked as a part-time driver for Sabeen and was also a police constable. He had been sitting in the rear seat when the attack on Sabeen Mahmud had taken place, as she was driving the car herself.
Ghulam Abbas was returning after offering prayers, when he was shot dead by armed assailants. The shooting took place in Korangi area of Karachi, where Abbas resided.
However, according to Umar Khattab, the murder of Abbas would not hamper ongoing investigation of the Sabeen Mahmud murder case. This was due to the fact that prior to his shooting, Ghulam Abbas had identified the criminals before a magistrate.
Sabeen Mahmud was shot dead in April of this year, after she hosted a controversial session at T2F cafe on the issue of Balochistan. It was Ghulam Abbas who had rushed Sabeen and her mother to the hospital, after both of them had been sprayed with bullets.
A graduate of IBA named Saad Aziz had confessed to being the mastermind of Sabeen Mahmud’s murder. The above named was also an accomplice in the infamous Ismaili bus attack.
