Here's an overview of the case before I provide you with a couple of Urdu links to the details, the first of which is a comprehensive report by BBC Urdu, published on the 26th of March (last month):
Taimoor Arshad Qazi, a manager at a renowned superstore in Dadyaal - namely D-Mart - then aged 29, was picked up in broad daylight from the store by a group of armed men who described themselves as from the 'agencies' (a euphemism for Pakistan's clandestine security agencies), on the 13th of July 2017, never to be seen or heard from again.
Here's the CCTV footage (4 videos):
On the 12th of December 2018, Mamoon (the abducted Taimoor's elder brother) wrote a series of letters to various organs of the Pakistani State, beseeching them to find his brother and present him before a court of law, but to no avail.
