A Rajshahi University teacher filed an attempted murder case on Thursday night against his colleague after the latter allegedly assaulted him.
Prof Ali Asgar of RU's crop science and technology department filed the case with Motihar Police Station against Prof Khairul Islam of the same department, said SM Masud Parvez, officer-in-charge of the police station.
"I was standing beside the dean's office when Prof Khairul came and hit me without saying anything. As a result, I fell on the floor and fainted," said Prof Ali.
However, Prof Khairul denied the allegation, claiming that he did not even touch him.
Both teachers had filed two general diaries against each other over another dispute with the police station in November last year.
