A 19-year-old NEET aspirant from Bihar, Aman Kumar Singh, went missing on the intervening night of May 11 and 12 from his PG accommodation in Rajasthan's Kota. "My exam didn't go well. Find me around Kota Barrage," a note he left purportedly read. CCTV footage reportedly showed him getting on a bike with another boy and reaching Kota Railway Station.
