Claim: Ramakrishna Biswas was one of the ones assigned to assassinate one Mr. Craig, the Inspector General of Police and killed the wrong person.
Evidence: Biswas and Kalipada Chakrabarty were assigned to this task. Surya Sen and his followers decided to assassinate one Mr. Craig, the Inspector General of Police for Chittagong. On 1 December 1930, they went to Chandpur station, but mistakenly killed a rail inspector, Tarini Mukherjee, instead of Craig.
