The lack of a database of CCTV footage has led to a huge drawback in the search of a special needs teen, Tarun Gupta, who went missing on October 1. Forum For Autism (FFA) members, who have been helping Vinod, planned to use facial recognition software to examine CCTV footage from cameras installed at Central Railway stations. However, taking it to each railway station is practically impossible, they say. They instead review each footage themselves.

FFA member Vijay Shree R, 42, said, "Tarun seems to be going from one place to another and we are always a few hours behind after we receive reports of his sightings. Either his father or we first go to the railway station where he is reportedly sighted and spend hours going through the CCTV footage. This is extremely time-consuming."
