While each day passes without them having an inkling about their son's whereabouts, the Railway Protection Force (RPF) have no clue of even the case, claimed Tarun Gupta's father, Vinod Gupta on Sunday. On Saturday, Vinod and a few family members went looking for Tarun at Palghar, Dahanu and Vapi railway stations.

Much to their shock, when they enquired with RPF officials at the stations about him, they seemed to have never even heard about the case. Not one RPF official knew anything about him. No one even had a photograph of him. This means the RPF have not sounded any 'alert'. RPF told me four days ago that an 'all India alert' had been sounded and that the search for Tarun would commence in a few hours," the 16-year-old autistic teen's father said. Tarun went missing from the vicinity of his Colaba home on October 1.
