Did Hriday Mondal actually hurt 'religious sentiments'?

Hridoy Chandra Mandal, a teacher of Munshiganj Sadar Upazila's Binodpur Ramkumar High School, has been released on bail.

On March 20, he was teaching a class at the school. He got engaged in conversations with his students about science and religion.

Two days later he was arrested for "hurting religious sentiments".

What exactly happened that he had to be in prison for 19 days? Was it a planned incident?

Will the teacher be able to return to his job after such an incident?

The Daily Star journalist Zyma Islam tried to get answers to these questions from Hriday Chandra Mondal in an exclusive interview in today's Star Connects.
