In April 1930 it was decided that the question of the release of Madan Singh and a few others of his type should come up for consideration when the prisoners had completed 20 years in jail, including remission. In September 1932 his case was again taken up and it was decided to have him interviewed by a C. I. D. officer and to bring him to the Punjab for this purpose. He is still in jail.
