What is the common element among Ram Prasad Bismil, Roshan Singh and Rajendra Lahiri ?

Ram Prasad Bismil, Roshan Singh, and Rajendra Lahiri were prominent members of the Hindustan Republican Association (HRA) who were executed for their involvement in the Kakori Conspiracy case [1]. On August 9, 1925, these revolutionaries looted the 8-Down train carrying government treasury funds near Kakori to finance their activities against British rule [2]. Following a massive crackdown, Bismil, Lahiri, Roshan Singh, and Ashfaqullah Khan were sentenced to death and hanged in 1927 [3]. While Bismil was a founder of the HRA, Roshan Singh and Rajendra Lahiri were participants rather than founders [2]. The Central Legislative Assembly bombing of 1929 involved Bhagat Singh and Batukeshwar Dutt, not the Kakori martyrs [3]. The Swaraj Party was established by C.R. Das and Motilal Nehru [4]. Therefore, their common link is their association with the Kakori case [1].
