 Police investigation of the killers connected them with Barin's country house in Manicktala (a suburb of Calcutta) and led to a number of arrests, including Aurobindo and Barin.The ensuing trial, held under tight security, led to a death sentence for Barin (later commuted to life imprisonment).The case against Aurobindo Ghosh collapsed after Naren Gosain, who had turned crown witness, was shot in Alipore jail by Satyendranath Basu and Kanailal Dutta, who were also being tried.
