Police arrested the accused, identified as Subhash Modad (22), on the charge of rape and the doctor couple for trying to hush up the matter and bribe the victim's kin to not report the incident to police as it would bring bad name to their hospital.
"The incident came to light after four days as the doctor couple detained the suspect and offered bribe to the victim's father for not reporting the incident to police," said Deputy Commissioner of Police Shahaji Umap.
The arrests were made on the complaint of the victim's father, he said.
Police said the medical examination of the woman, conducted by a government hospital, has confirmed rape.
While Modad was booked under section 376 (d) (intercourse by any member of the management or staff of a hospital with any woman in that hospital), the Sonawane couple under sections 213 (taking gift, etc, to screen an offender from punishment) and 214 (offering gift or restoration of property in consideration of screening offender, of the Indian Penal Code.
A local court on Saturday remanded Modad in police custody till April 26 and the doctor couple till April 21.
