Of them, about 85,000 are in Dhaka and 500 in southern Khulna.
Meanwhile, city life returned to almost normal as curfew in six cities, including capital Dhaka, was relaxed for 17 hours on Saturday.
The indefinite curfew was imposed from Wednesday night to contain the student demonstrations.
In a pre-emptive move, the government shut down all universities and colleges in six cities.
Security forces arrested five teachers, two from Dhaka University and three from Rajshahi University late on Thursday night. They are, Anwar Hossain, DU Teachers Association general secretary and Harun-Al-Rashid, Dean of social sciences; Saidur Rahman Khan, former vice-chancellor of northern Rajshahi University, Abdus Sobhan, convener of the Rajshahi University Progressive Teachers' Community and Molay Kumar Bhawmuk, an associate professor.
A court on Saturday sent Anwar Hossain and Harun-Al-Rashid into a four-day police remand for questioning, about 36 hours after they were arrested. They are facing charges of “illegal attacks and property damage” tied to violence. Dhaka’s chief metropolitan magistrate’s court also approved a five-day remand for Azizul Bari Helal, president, Jatiyatabadi Chhatra Dal, student wing of Khaleda Zia’s Bangladesh Nationalist Party (BNP).
The US-based Human Rights Watch (HRW) has, meanwhile, urged the Bangladesh government to respect international human rights standards as it enforces a curfew.
It said anyone detained under the emergency regulations must be charged with a cognisable criminal offence or released, and that anyone mistreated in detention should be able to seek and obtain an effective remedy before competent authorities.
