After initial investigations confirmed what Feringhea had said, Sleeman began an extensive campaign using profiling and intelligence. Sleeman was made superintendent of the Thuggee and Dacoity Department in 1835, an organ of the Indian government first established by the East India Company in 1830.[9] (Dacoity referred to organised banditry, distinguished from thugs most notably by its open practice and due to the fact that murder was not an intrinsic element of their modus operandi.) Sleeman developed elaborate intelligence techniques that pre-dated similar methods in Europe and the US by decades.[10] During the 1830s, the thugs were targeted for eradication by the Governor-General of India, Lord William Bentinck, and his chief captain, William Henry Sleeman.[citation needed]
