The victim, identified as Subhash and a resident of Bhadoda village, was shot at by four miscreants last night, while he was on his way to home after closing his clinic at Raasna chowk here, police said.
The doctor was rushed to a local hospital where he was declared dead.
However, no complaint in this connection has been registered by Subhash's family so far, police said.
According to police, an old rivalry between two residents of Bhadoda village -- Yogesh and Udham Singh -- can be the reason behind the murder.
