Mumbai: Police probing the double murder case of artist Hema Upadhyay and her lawyer Harish Bhambhani fear that something "bad" might have happened with the prime accused Vidyadhar Rajbhar who is on the run since the crime came to light two weeks back.

Police also said that Hema's estranged husband Chintan Upadhyay, arrested for allegedly plotting the murders, is not opening up during investigation and apparently knows how to dodge questions. Chintan is currently in police custody till January 1.
