Hospital sources said Sen was discharged at 9.55 pm and was taken to her home in an ambulance amidst tight security.

The cabin in the nursing home's ICU and all entrances was under tight security in view of a woman's attempt to enter her cabin during her stay there.

The 77-year-old reclusive actress, who has often been compared to Greta Garbo who also preferred to remain in her cocoons, has not been seen in public since her retirement from the film world in the late 1970's.

Sen, who featured in romantic partnerships on screen with late Bengali megastar Uttam Kumar from the 50s to the 70s and in Hindi films like Aandhi, was admitted to the nursing home on February 25 night.
