Rights organisation Amnesty International yesterday demanded reinstatement of Dhaka University Prof Morshed Hasan Khan, who was terminated on September 9 on charges of distorting the country's history and defaming Bangabandhu Sheikh Mujibur Rahman.
Morshed was a teacher of marketing department and a leader of BNP-backed teachers' panel.
Amnesty also demanded his and his family's safety and security as he has received multiple death threats from unidentified people, and is being denied access to his campus residence, where his wife -- a cancer patient -- resides.
"Professor Morshed got terminated merely for exercising his right to freedom of expression, which was to publish an opinion editorial in a national newspaper," claimed Amnesty International.
"It is alarming that an academic is facing life imprisonment only for exercising his right to freedom of expression," it added.
Amnesty sent a letter to President Abdul Hamid, with a demand of dropping all charges against the professor and to respect, protect, and fulfill the right to freedom of expression.
