Kala Singh, son of Gulab Singh was a resident of Amritsar. His father was a Carpenter by profession. Kala Singh took an active part in anti-British activities. He was involved in the first Lahore Conspiracy Case of 1915. He took part in Chabba Dacoity.
The first in the series of dacoity was attempted on 23 January 1915 at village Sahnewal in Ludhiana District, followed by a 27 January attack at village Mansuran of the same district, 29 January at Jhanir (Manerkotla), and the fateful one at Chabba (Amritsar) on 02 February 1915. He participated in Chabba dacoity but unfortunately, he was captured on the spot. Bombs and pistols were used in this dacoity and when captured he had in possession two cartridges. In the Chabba dacoity, Surain Singh, one of the participants who have a personal enmity with the head of a family, quietly left the group of Kala Singh, came back and killed him. Amritsar Police got ed and they were able to plant a police agent namely Kirpal Singh at the party. Indeed this particular dacoity proved to be the main event responsible for the failure of their further missions.
Kala Singh was trialed and convicted under Sections 121, 121A, and 396 of IPC, and on 13 September 1915 he was sentenced by the Lahore Tribunal to death and forfeiture of property. Later on, his sentence was reduced by the Lieutenant-Governor to transportation for life. He was deported to Cellular Jail at Port Blair in the Andaman Islands in 1916.
