Hours before her death, Dr Payal Tadvi was still being yelled at, taunted and insulted by one of the three senior doctors — Dr Hema Ahuja — accused of abetting her suicide through casteist harassment. The last telephonic conversation between Dr Tadvi and Dr Ahuja was what triggered her into taking the extreme step, Dr Tadvi's parents have now alleged. However, police investigators have said they are going to have a tough time proving caste atrocity as it has not been mentioned in Dr Tadvi's suicide note.

The charge sheet filed by the Mumbai crime branch has details of Dr Tadvi's last phone conversation. Dr Ahuja, it states, called Dr Tadvi at 04:51 pm on May 22 and the conversation lasted for one minute and 46 seconds. Dr Tadvi was in the ward when Dr Ahuja called her.
