“Utpal sir had caught the student (prime accused) with a girl inside a classroom and informed the family of the girl about the matter, which had created anger in him. That’s the reason why the student beat up Utpal sir to death on the sports day,” said a student of the college.
According to the college authorities, no CCTV footage of the crime was found as the cameras recorded nothing at that moment due to power outage.
The college authorities suspect that the boy had disconnected the power supply before killing Utpal.
Utpal Sarker, 35, son of Ajit Sarker of Engeldani village under Sirajganj’s Ullapara police station, had been serving as a teacher of Haji Yunus Ali School and College for almost ten years.
