Chandra Shekhar Tiwari(23 July 1906 – 27 February 1931), popularly known as Chandra Shekhar Azad, was an Indian revolutionary who reorganised the Hindustan Republican Association (HRA) under its new name of Hindustan Socialist Republican Association (HSRA) after the death of its founder, Ram Prasad Bismil, and three other prominent party leaders, Roshan Singh, Rajendra Nath Lahiri and Ashfaqulla Khan. He hailed from Badarka in Unnao district of Uttar Pradesh and his parents were Sitaram Tiwari and Jagrani Devi. He often used the pseudonym "Balraj" while signing pamphlets issued as the commander-in-chief of the HSRA.
On 27 February 1931, the CID head of the police at Allahabad, J. R. H. Nott-Bower was tipped off by someone that Azad was at Alfred Park and was having a talk with his companion & aide Sukhdev Raj. On receiving it, Bower called on the Allahabad Police to accompany him to the park to arrest him. Azad's old comrades Veerbhadra Tiwari and Yashpal were also held responsible for tipping off two of the police constables. The police arrived at the park and surrounded it from all four sides. Some constables along with DSP Thakur Vishweshwar Singh entered the park armed with rifles and the shootout began. Azad asked Raj to move out in order to carry on his legacy and work in the party, Azad gave him cover fire and Raj moved out safely. Azad hid behind a tree to save himself and began to fire from behind it. The police fired back. After a long shootout, holding true to his pledge to always remain Azad (Free) and never be captured alive, he shot himself in the head with his gun's last bullet. In the shootout, Bower and DSP Singh were injured in the right palm and jaws respectively. The police recovered Azad's body after the other officers arrived at the site. They were hesitant to come close to Azad even after finding him dead.
The body was sent to Rasulabad Ghat for cremation without informing the general public. As it came to light, people surrounded the park where the incident had taken place. They chanted slogans against British Raj and praised Azad.
