Claim: Ramakrishna Biswas was one of the ones assigned to assassinate one Mr. Craig, the Inspector General of Police (senior police officer in the police force) and killed the wrong person.
Evidence: On 1 December 1930, they went to Chandpur station, but mistakenly killed a rail inspector, Tarini Mukherjee, instead of Craig. Surya Sen and his followers decided to assassinate one Mr. Craig, the Inspector General of Police for Chittagong. Biswas and Kalipada Chakrabarty were assigned to this task. An inspector-general of police is a senior police officer in the police force or police service of several nations.
