After his release, he founded a gymnasium and recruited many youths for the revolutionary movement led by Surya Sen. On 18 April 1930, he was one of the leaders of the Chittagong armoury raid. After the incident, he was able to flee from Chittagong with Ganesh Ghosh and Jiban Ghoshal. After a short encounter with police in Feni railway station, he took shelter to French territory Chandernagore.

In the trial, he was sentenced to transportation for life and sent to the Cellular Jail in Port Blair. After, a long hunger strike in the Cellular Jail in 1932, he was brought back to a mainland jail along with a number of his fellow political prisoners due to an initiative undertaken by Mahatma Gandhi and Rabindranath Tagore. After his final release in 1946, he joined the Communist Party of India.
