Ashraful Ahsan Zitu alias Zitu Dada attacked his teacher, Utpal Kumar Sarkar, to show heroism to his girlfriend, as the victim forbade the duo to roam together.
Commander Khandaker Al Moin, director (Legal and Media Wing) of the Rapid Action Battalion (RAB), stated this to reporters in the capital on Thursday, following Zitu's arrest from Shreepur in Gazipur on Wednesday evening.
Four days before the incident, Zitu and his girlfriend were roaming together on the premises of Haji Yunus Ali School and College at Ashulia, on the outskirts of the capital. Utpal Kumar, president of the discipline committee of the institution, forbade them not to roam together.
Zitu became enraged with the teacher over this restriction imposed on him. Later, he planned to attack the teacher to impress his girlfriend with his heroism.
While his girlfriend is a college student at the same institution, Zitu is a 10th grader.
On June 25, while a cricket match between two teams of female students was taking place on the school playground, Zitu repeatedly hit Utpal Kumar with a cricket stump.
The teacher succumbed to his injuries at the Enam Medical College Hospital in Savar on June 27.
After starting his schooling, Zitu took a break from his studies and was admitted to a madrasa. After passing Junior Dakhil, he left the madrasa and was admitted to the ninth grade of the school in 2020.
Although it had been assumed that Zitu was a minor, the Rapid Action Battalion claimed him to be a 19-year-old youth.
He was an unruly student. Various allegations of different misdeeds, such as conflict, violation of discipline, and eve-teasing, were raised against him.
He used to smoke cigarettes on the school premises and did not wear a uniform. He also rode his motorcycle desperately.
He led a teenage gang in his area. It was known as the "Zitu Dada Gang." If anybody complained against him to his family, he and his gang members carried out attacks on him or her.
When Zitu learned that the teacher's condition was critical, he left his area and fled to Manikganj, where he sought refuge at the home of a relative.
The following day, he travelled to Pabna before arriving in Gazipur to hide at his friend's residence there.
Teachers from 21 schools and colleges formed a human chain outside the Savar Upazila Parishad gate after learning of Zitu's arrest and demanded that the offender receive exemplary punishment.
