Nrisinghaprasad Sarkar(1906-?), son of Ashwinikumar Sarkar, was born in Balladighi village of the undivided Nadia district; but lived mostly in Krishnanagore. He studied at Debnath School and Krishnagore Collegiate School followed by Krishnagore College for his B Sc degree (1928).
As a school student, he was indoctrinated to nationalist ideology by martyr Anantahari Mitra; and through him met Subhas Chandra Bose and Bipinbehari Ganguly. In 1923, he participated in a social welfare service in Aranghata village led by Krishnagore Athletic Club.
Next year, with Taradas Mukhopadhyay and Pramodranjan Sengupta, he smuggled out potassium chlorate and other acids from his college laboratory by sneaking through the exhaust hole in the night. The bombs they prepared with these chemicals were thrown on the residences of the police super, intelligence inspector Rabi Roy, and the police station of the town. He trained the youth how to use a revolver with the one he received from the martyr Anantahari Mitra before his arrest.
He left his job in the Sonpur Raj to devote himself fully to revolutionary activities in Nadia. He had to leave his home since his father was a government employee and lived in the house of Nirmalnalini Ghosh, a Congress leader of Krishnanagore. In 1930, he was arrested under the Bengal Criminal Law Amendment Act which empowered the government to imprison anyone without trial. He was kept in different jails in Bengal for seven years, in addition to three months of rigorous imprisonment for breaking rules in the jail.
