The video shows Sarfaraz Shah in a black T-shirt being dragged by his hair in a public park by a man in plain clothes.
The Rangers appeared to be "hyper", and their physical and mental condition could not be ascertained by an independent medical examination, as they were taken into "protective" custody by their own comrades.
Ali Dayan Hasan, the Pakistani researcher for Human Rights Watch, said the killing "provides chilling evidence of the abusive, trigger-happy practices of Pakistan's military, paramilitary and civilian agencies".
Also shortly after the incident, the chief of the Sindh Rangers, Fayaaz Leghari, was fired from his post by the Pakistani Government on orders of the Supreme Court.
[5] Shahid Zafar, the Ranger who shot Sarfaraz Shah, was convicted of murder in the Sindh High Court where he was later sentenced to death after being found guilty of the offence.
[6][7] The Ranger and his lawyer later appealed the verdict in the Supreme Court of Pakistan which upheld the death sentence against the accused upon reviewing the case, while punishments for others involved were adjusted.
