Brin Tusk was a Bajoran who lived on Terok Nor during the Cardassian Occupation of Bajor.

In 2366, Brin was arrested and placed in a holding cell for an unknown crime. While in the holding cell, Brin and two other Bajorans were informed by Odo that they were to be sentenced to five years hard labor following a sentence confirmation trial. (DS9: "Things Past")
