It took seconds for this quick-thinking commuter to yank a 17-year-old girl to safety after she fell off a running train. Videos of the miraculous rescue had gone viral on social media in October and, yet, no one knew his name. It was after more than two months of searching, and sifting through 600 phone calls, that this unsung hero's identity has finally been revealed - Istakhar Ahmad, 52, a resident of Govandi who works at a furniture shop in Chembur.

Less than a second
The viral video showed the girl leaning out from the footboard of a moving train. When a train passed by on the parallel track, she slipped and fell. One of the commuters, now identified as Ahmad, was standing near the door and managed to grab her hand and pull her to safety.
