His death in custody raised wide suspicion across the country and demands for an independent inquiry were raised, including earnest requests from his mother, Jogamaya Devi, to Nehru. The prime minister declared that he had asked a number of persons who were privy to the facts and, according to him, there was no mystery behind Mukherjee's death. Devi did not accept Nehru's reply and requested an impartial inquiry. Nehru, however, ignored the letter and no inquiry commission was set up. Mukherjee's death, therefore, remains a matter of some controversy.
