Police however failed to arrest anyone in this connection.

Alim in his complaint said on January 22 his departmental office received a letter in which he along with Chairman Rabiul Islam and Julfiquar Ahmed was warned that if they do not give first class marks to some students loyal to Islami Chhatra Shibir in masters examination, they (teacher) will have to face dire consequences.

Referring to the letter Alim said, "The terrorists made an abortive attempt to kill me."

Prof Rabiul, accompanied by other teachers of the department, met with Vice-chancellor Altaf Hossain yesterday and sought impartial investigation of the attack.

He also requested the VC to ensure security of other teachers.

Prof Altaf assured them that university administration would take up the matter seriously.

Meanwhile, some pro-Jamaat teachers of the department are saying that Alim was a victim of snatching.

Talking to newsmen, Proctor Enamul Haque said police are still posted at the residence of Alim, a newly recruited lecture, who was stabbed by unknown assailants on his way home at Binodpur from the Jubery Teacher's Club on the campus.

He is undergoing treatment at his residence.
