Rehan Sharif, a teacher in the community medicine department of Shaheed M Mansoor Ali Medical College, Sirajganj, who came into limelight after shooting a student, was carrying illegal weapons for a long time.
He often threatened to shoot those who disagreed with his views, but no action was taken against him.
The teacher was dismissed from his previous workplace, North Bengal Medical College and Hospital, Sirajganj, for threatening a senior colleague at gunpoint.
The students alleged that he would often threaten them while he was welding his pistols at his current workplace. Amirul Hussain Chaudhary, principal of Mansoor Ali Medical College, said, after receiving verbal complaints, the college authorities served show cause notices to the teacher twice, to which the teacher did not respond.
The principal claimed that he could not take any action against Raihan Sharif due to his connections with influential people.
Rehan Sharif shot student Arafat Amin during an oral examination in the college on Monday afternoon. On information, police reached the spot and recovered two foreign pistols, 81 rounds of bullets, four magazines and 12 foreign knives from him.
Police said that there are two cases against Rehan Sharif. The victim's father Abdullah Al Amin has filed a case accusing the teacher of trying to kill him as well as threatening his son. In this case, Rehan Sharif gave a confessional statement before Judge Billa Hussain in the Additional Chief Judicial Magistrate Court of Sirajganj.
Sirajganj Police Detective Branch Inspector Abdul Wadud registered another case under the Arms Control Act. The police sought seven-day remand for the teacher, which the court did not grant as he had given a confession in another case.
