The Central Bureau of Investigation (CBI) holds an annual lecture and gives out awards in memory of D P Kohli, its founder director. This time around, Kohli’s family has decided to give the CBI the revolver which once belonged to the late officer. The CBI plans to keep the .38 Smith & Wesson in its museum in Ghaziabad — the museum has around 1,300 exhibits of which 500 are on display.
