Dhaka University Teachers' Association has expressed concerns over harassment, physical and mental torture on Rozina Islam and condemned such incident taking place inside the Secretariat.
A statement by the association said, the health ministry alleges that Rozina took photos of confidential files from HSD Private Secretary's room. The Personal Secretary meets general people in that room. If confidential files are put in a place where the general public have access to, then it is negligence on the authority's part.
The association also demanded fair investigation of the incident and punishment of the accused people behind the incident.
They also urged government to ensure legal protection and human rights of the journalist.
Prothom Alo Senior Reporter Rozina was kept confined at the health ministry for more than five hours on Monday before being handed over to police.
Later, she was shown arrested in the case on charges of spiriting away "important" documents.
Investigative journalist Rozina, known for dozens of ground-breaking reports in her career, was charged with breaching the Official Secrets Act 1923.
Rozina Islam is known for her strong reportage of official corruption. She has recently made several investigative reports revealing corruptions in the health sector.
