On 30 January 1948, Godse assassinated Mahatma Gandhi with a black Beretta M1934.[3] Parchure reportedly celebrated Gandhi's assassination by distributing sweets. On 3 February he was detained and was charged with assisting in Gandhi's murder by providing Godse with the murder weapon.[6] On 18 February 1948 he was formally arrested on charges of criminal conspiracy under section 120B, 109 and 114 of Indian Penal Code.[7]
Before the Magistrate of Gwalior, he made a confession in which he accepted the charges laid on him. He stated that he had acquired the pistol from Gangadhar Dandavate, and passed it on to Godse. Godse, along with Narayan Apte, was stated to have travelled from Delhi to Gwalior by train on 28 January 1948 to obtain a pistol. Godse wanted an automatic pistol to replace his own unreliable pistol. Parchure offered him the semi-automatic Beretta, which Godse experimented with in Parchure's back yard, and then purchased for ₹ 300. Parchure stated that the pistol had originally belonged to Deshmukh, an officer in the Gwalior State Army who had acquired the pistol in Germany. Godse and Apte then left for Delhi on 29 January.[2]
Based on this confession, Parchure was initially sentenced to life imprisonment by a lower court on 10 February 1949.[8] Madanlal Pahwa, Vishnu Karkare, Gopal Godse, and Shankar Kistaiya were given the same sentence. Savarkar was acquitted and Digambar Badge was pardoned for his deposition against others, while Nathuram Godse and Narayan Apte were sentenced to be hanged. Parchure, however, appealed the decision in the Punjab High Court, stating that his confession had been coerced from him, and that he had no part in the conspiracy.[2] He said that he had met Godse and Apte in Gwalior when they travelled there for work related to recruiting volunteers for the HRS. Both Godse and Apte concurred with Parchure's fresh statement, and Godse stated that the pistol was acquired by him from a dealer in a refugee camp in Delhi. As a result, Parchure was acquitted in June 1949 by a bench of three judges who stated that there was no evidence of his involvement.[2] Kistaiya was also acquitted as he was found to be working only as a servant of Badge and not as an accomplice.[9] The sentences of the other five were retained by the High Court.[8]
After his release from jail, Parchure was banned from Gwalior. However, he returned there in 1952 on the condition of not participating in political activities.[2] He later restarted his medical practice, and died in Gwalior in 1985.[2]
