Trelos Vren was an inhabitant of Deep Space 9 as well as a thief who kept on getting caught by Odo, but was very persistent. He was once arrested for trying to break into the assay office on the station. Later on, in 2372, he was arrested outside the Klingon restaurant and Odo held him on four accounts of petty theft. Odo reviewed the case with Kira Nerys, joking that one might "have to admire his persistence" even though he wasn't successful in his endeavours. (DS9 episode: "Indiscretion")
