Madhya Pradesh police are using 'ghost stories' to extract information from a 50-year-old man, who is accused of robbing and killing several truck drivers across four states. Aadesh Khamra and his two accomplices are accused of killing at least 33 truck drivers and cleaners (drivers' assistants) since 2010. They were arrested last week.

Initially, interrogators found Khamra to be a tough nut to crack, but when they started telling him that ghosts of his victims are haunting his family, he began to give information, said a police officer. The interrogators told him yesterday that his son has met with accident twice in the last four months because the ghosts of those he killed are now after his family, said a police officer privy to the probe.
