On April 8, 1929, Bhagat Singh and Batukeshwar Dutt, members of the Hindustan Socialist Republican Association (HSRA), threw two bombs and scattered leaflets in the Central Legislative Assembly in Delhi. Their aim was not to kill but to "make the deaf hear" and protest against the Public Safety Bill and the Trade Disputes Bill, which they saw as oppressive laws aimed at curbing civil liberties and workers' rights.
