The Samed Police Station, the Tehran Rail Transport Department, the Revolutionary Guard, plus the Savama Secret Police—more than five hundred people in total—formed a massive task force that began an in‑depth investigation of the explosion site. The sheer number of lighting devices alone was enough to illuminate the night sky for several kilometers around.
Ghabari could be said to be a man of his word.
Gu Ji followed Hasha and participated in the entire investigation operation, personally watching as police and forensic technicians cleared the wreckage piece by piece. At the same time, experts in railways and explosives were constantly using this information to simulate the real cause of the explosion at every moment.
"Sir, it's been five hours. We've collected 3,500 kilograms of explosion debris and 337 items of explosive residue from the scene. We still haven't found any timing or remote‑control device, nor any remaining explosive compounds. There aren't even traces of a fuse."
