The police have been unable to trace the parents of controversial probationary IAS officer Puja Khedkar in a land dispute case registered against them after a video of her mother threatening a farmer with a pistol in Pune district went viral, a senior official said on Monday.

A team of Pune Rural police visited the bungalow of Manorama and Dilip Khedkar in the Baner area of the city in the morning. But it was unable to enter the premises as there was no response, and doors were locked from the inside, the official said.
