Bhagat Singh and Batukeshwar Dutt threw bombs at the empty treasury benches, being careful to ensure that there were no casualties in order to highlight the propagandist nature of their action. They made no attempt to escape and courted arrest while shouting "Inquilab Zindabad" (Long Live the Revolution) and "Samrajyavad Murdabad"' (Down with Imperialism). Their rationale for the bombing was explained in a leaflet titled "To Make the Deaf Hear" (paraphrasing the words of Édouard Vaillant). This leaflet was also thrown in the assembly and was reproduced the next day in the "Hindustan Times". On 15 April 1929 police raided the HSRA's bomb factory in Lahore and arrested Kishori Lal, Sukhdev Thapar and Jai Gopal. The Assembly Bomb case trial followed and Bhagat Singh, Sukhdev and Rajguru were hanged on 23 March 1931 for their actions.
