The address on the key ring was that of a trader in West Delhi. The trader told the police that Raj Kumar, an employee of his friend Rajiv Bansal, was missing. Bansal was a share broker, who said that Raj Kumar met several people daily on his behalf to recover money. The interrogation of the people he met when he was last seen led to the arrest of Manprit Singh and his brother Preet Singh of Janakpuri.

Both of them had bought shares from Bansal and the recent downslide in the market had hit them badly, police said. The pressure from Raj Kumar to pay up led to the crime, they said.
