[1] 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.

At that time, another revolutionary nationalist Pritilata Waddedar was staying in Kolkata and was asked to meet Biswas.
