"We cannot understand that being a lawyer and important person of the government how could Mainul term the Bangabandhu killing as 'an old political incident' and the case is not on the government's priorities," they said in a statement.

The teachers said Mainul's terming the killing of Bangabandhu and the subsequent case as 'political incident' has hurt the people and is tantamount to showing his sympathy to the killers of Bangabandhu instead of showing neutrality.

"Perhaps, he has mixed up the Bangabandhu killing with the killings that took place at different times at Ittefaq Bhavan," they said.

The statement urged the chief adviser to caretaker government to keep vigilance so that the implementation of the verdict of the case is not disrupted by any 'illegal intervention or influence' of anyone.
