Assistant Professor Hasina Begum, who teaches economics, has been appointed as the acting principal of Viqarunnisa Noon School and College.
The move came at a meeting held on Friday night amid growing student protest over the death of Aritree Adhikari.
On Wednesday, the Ministry of Education sent a letter to the police and Rapid Action Battalion (Rab) directing them to take legal action against three teachers of Viqarunnisa Noon School and College for their rude behaviour with Aritree Adhikari that prompted her to commit suicide.
The three teachers are suspended Principal Nazneen Ferdous, morning shift in-charge Jeenat Akhter and class teacher Hasna Hena.
Meanwhile, the Education Ministry has sent another letter to the Dhaka Education Board Chairman for taking departmental actions, including their suspension, against the teachers.
Earlier, the previous principal Nazneen Ferdous has been fired from the position on charges of instigating the ninth grader Aritree Adhikari to take her own life.
