A seven-year-old child was scorched as a maktab (centre for elementary Arabic learning) teacher allegedly threw hot water from a flask at him.
The incident took place on Tuesday, but the family filed a case about it last night after the child's father came back from his workplace in another district.
The victim is Shahriar Nafis, son of Ekhlas Uddin of Hemu Majhpara village of Jaintiapur upazila in Sylhet and a second-grader of Hemu Government Primary School.
About the incident, the child's father said, "The teacher scorched his skin with hot flask water as punishment for talking with another student of the maktab".
The maktab teacher, Abdul Karim alias Rezaul Karim (27) is also a teacher of nearby Darul Ulum Hemu Madrasha.
After the incident, the child's mother took him to local pharmacy and treated him there, but did not file any complaint. The father came home on Wednesday and met with local Union Parishad member next day, who suggested him to file a case.
The victim's mother Safia Begum filed a case accusing teacher Rezaul Karim alias Abdul Karim, confirmed Jaintiapur Police Station officer-in-charge Mohsin Ali.
"Police in primary investigation is convinced that Karim is the culprit. We have already started looking for him," the OC told this newspaper last night.
