Search for missing autistic teenager Tarun Gupta has taken an optimistic turn over the past 10 days. According to the 16-year-old's father, Vinod Kumar Gupta, nearly 20 people have called him or his relatives over the past few days, to report sightings of his lost son. All sightings have been from the Jamnagar-Baroda-Ahmedabad region.

"We will find him any day now," said a hopeful Gupta. "About a month-and-a-half ago, Tarun was aboard the Devagiri Express, which runs between Mumbai and Secunderabad. He was in the AC compartment. I came to know this because the train ticket collector called me eight days ago. When the train neared Vasai, he saw posters and stickers announcing that Tarun was missing alongwith a number to call on in case he was sighted. He told me that Tarun was in the AC coach for two to three hours; passengers started complaining about him so he went and sat near the toilet...and that he had got off at Jamnagar, which is where the train route ends."
