Who threw two bombs on the Door of the Central Assembly in New Delhi on April 8, 1929?

Bhagat Singh also disapproved that the two should be escorted after the bombing by the rest of the party. On 8 April 1929, Singh and Dutt threw a bomb onto the corridors of the assembly and shouted “Inquilab Zindabad!” (“Long Live the Revolution!”). This was followed by a shower of leaflets stating that it takes a loud voice to make the deaf hear.
