The Ranga Billa Kidnapping Case was a notorious crime in New Delhi in 1978. Two children, Geeta and Sanjay Chopra, were kidnapped by two young men, Ranga Khus (Kuljeet Singh) and Billa (Jasbir Singh), who planned to demand ransom from their parents. Their plans went awry when their car was involved in a traffic accident with a public bus. They subsequently raped Geeta, murdered the children and fled the city. They were arrested on a train a few months later, tried and hanged for the crime in 1982.
