The Killer Car - Part 1 - S1.E57

The team of CID is called at night when a man called Dibkar is killed by a man called Raj with his car that he was driving without his headlights on. They arrest Raj, but later Dr. Salunke informs them that Raj could not have killed Dibakar, as he died by getting hit by a white car. ACP Pradyuman is soon contacted by an old couple who tells him that they too were almost killed by this white car whose driver was a young boy. They also told him that the car had an unusual musical reversing horn. Will the unusual clue be enough?
