A headmaster in Adamdighi, Bogura, was physically assaulted by a tenth-grade student named Hridoy Hossain after he was instructed not to use his mobile phone in class. The injured teacher, Atiar Rahman, later filed a police case against Hridoy and three others. In protest, a large number of students formed a human chain on the school grounds and in front of the Upazila Parishad on Monday afternoon, demanding justice. A memorandum was also submitted to the UNO seeking disciplinary action.
