Several protests were staged in the capital Dhaka and elsewhere in Bangladesh on Monday, but they were only a fraction of the size of those seen earlier in the month.
Police charged with batons to break up one protest on Dhaka’s outskirts, arresting at least 20 people, newspaper Prothom Alo reported.
Security forces were deployed widely elsewhere in the teeming megacity of 20 million to deter other demonstrations.
Students Against Discrimination leaders had vowed to end a week-long moratorium on new demonstrations if police failed to release their leaders by Sunday evening.
The group’s demands also include a public apology from Hasina for the violence, the dismissal of several of her ministers, and the reopening of schools and universities around the country that were shuttered at the height of the unrest.
At least 9,000 people have been arrested nationwide since the unrest began, according to Prothom Alo.
Troops are still patrolling urban areas and a nationwide curfew remains in force but it has been progressively eased since the start of last week.
Bangladesh’s mobile internet network was restored on Sunday, 11 days after a nationwide blackout imposed at the height of the unrest, in another sign of the government’s confidence that it was in control of the situation.
