She was released from jail following interim bail in an Official Secrets Act case
Prothom Alo Senior Reporter Rozina Islam has expressed her gratitude to all who stood beside her.
"I have no words to express my gratitude to them. Thank you all for being by my side," the Bangla daily quoted her saying.
Islam was released from the Kashimpur Women's Central Jail in Gazipur on Sunday after a Dhaka court granted her bail in a case filed under the colonial-era Official Secrets Act by the Health Ministry.
She was taken to the Square Hospital in the capital where she's now undergoing treatment as an inpatient.
Her husband Monirul Islam said she has been taken to the hospital as she was feeling unwell. "Tests are being done as per the advice of the doctor."
Her condition is stable, according to doctors.
Dr Shahadat Hossain of the hospital's Emergency Department said that the Prothom Alo reporter was very weak.
"She is being treated under Dr Raihan Rabbani, consultant of Internal Medicine and intensive care unit. We will take next steps after the tests come back," he added.
On May 17, Rozina Islam was allegedly confined by some Health Ministry officials for five hours inside an official's room at the secretariat.
Later, charges of "stealing" official documents and "taking photographs" of confidential documents were brought against Islam, an award-winning investigative journalist.
The next day, a Dhaka court sent her to jail after rejecting the police's remand plea.
Her harassment at the ministry and subsequent arrest have sparked protests by journalists, teachers, intellectuals, politicians, and rights organizations across the country and abroad.
The Health Ministry said it has opened an inquiry over the incident. A three-strong panel was supposed to submit its findings in three working days but is yet to do so.
On May 19, the Detective Branch was given charge of the investigation.
