He said that Indira Shelar lived alone in her suburban Vile Parle flat and the fall had rendered her immobile and she was unable to come to the door and reach out for help.
The police was informed about the incident by neighbours who grew concerned after not seeing Shelar around for the past three days, the official said.
He said that fire brigade and police personnel who broke open the door to Shelar's flat found her lying near the bathroom door.
