The 71-year old missionary of a Nadia convent, who was raped last Saturday, left West Bengal by an early morning flight on Friday.
"She took an Indigo flight for Delhi," said a security official at the airport.
The nun was discharged early Friday morning from the Ranaghat sub-divisional hospital, where she was admitted on last Saturday. She was escorted to Dumdum airport straight from the hospital.
"She was discharged at 2:20 am on Friday, and a gynaecologist escorted her to the airport," said Dr Atindranath Mondal, the super of the hospital. The timing was intended to hoodwink the media.
Ranaghat sub divisional officer Rajarshi Mitra and the subdivisional police officer were present at the time of discharge.
The convent authorities submitted a written application to the hospital stating they want to take her away. According to airport sources, the flight left around 6 am.
Hospital sources told HT that during the course of her treatment, the mother superior of Convent of Jesus and Mary told the superintendent of the hospital that she will not stay in the state any longer.
The departure of the missionary from the state will further embarrass the state administration that is under extreme pressure for not being able to nab any of the eight culprits even a week after the incident, even though the faces of four of them were clearly captured by the CCTV cameras in the campus.
The growing pressure on the government compelled chief minister Mamata Banerjee to hand over the probe to the Central Bureau of Investigation, the first such decision during her regime.
