She is the country's first swine flu death.
But angry and emotional family members of the girl threatened to sue the hospital for criminal negligence.
Union Health Minister Ghulam Nabi Azad also said the treatment came 'too late' to save the girl, while Maharashtra Chief Minister Ashok Chavan squarely blamed the hospital for Rida's death.
Chavan said the government would take action against the hospital for the 'lapses' that led to the girl's death.
The Maharashtra authorities also began probing the probable lapses on the part of the private hospital, where the girl was admitted July 27, and also issued notice to Ruby Clinic where the girl's blood tests were conducted.
