Yur T'aug was a male Bothan who lived on the planet Coruscant during the waning years of the Galactic Republic. T'aug served as a police officer with the Coruscant Security Force and, by 43 BBY, had achieved the rank of captain. T'aug was in charge of the investigations into the homicides of Senator Uta S'orn's son, Ren S'orn, and a petty thief and informant named Fligh. Both were the results of several killings on Coruscant in which the victims were drained of blood before being killed. Throughout the investigation, T'aug clashed with Jedi Qui-Gon Jinn and Obi-Wan Kenobi on how the CSF was treating the cases.
