A teacher at a private school in Siraha has been taken into custody after allegedly beating a 13-year-old student, police said on Friday.

The incident occurred at Apex Vidyamandir in ward 7 Golbazar Municipality. The student, Abhinash Yadav, a grade 8 pupil from ward 3 of Naraha Rural Municipality, was reportedly assaulted by teacher Santosh Gupta, leaving him with bruises on his face, back and thighs.

“He is undergoing treatment at a private hospital in Golbazar,” said the student’s father, Suresh Yadav, adding that the boy was beaten as he raised concerns over the quality of teaching.

Govinda Sah, chief of the Golbazar Area Police Office, said police detained Gupta following a complaint from the family and are investigating the case.

School officials were not immediately available for comment despite repeated attempts to contact them.
