Tax collector

In the episode Imprisoned, when Sokka, Katara , and Aang are talking with Haru and his mother, a Firebending soldier came to their house. Sokka peaks out the window and sees that it is a Fire Nation soldier. Moments later when the soldier is inside the house, he asks Haru's mother for her taxes. She tells him she already paid him, but he threatens to burn her house down if she doesn't give him the money. So Haru's mother gives him the money taking the silver pieces with him, and dropping the copper pieces on the floor. He is seen later in the episode when he arrests Haru in the middle of the night.
