Leosa

From Memory Alpha, the free Star Trek reference.

Leosa was a dabo girl hired by the Ferengi Nunk to pose as a teacher and seduce Reginald Barclay. Her mission was to steal Barclay's hologram from the Pathfinder Project so that Nunk could acquire Seven of Nine's nanoprobes. When his hologram was stolen, Barclay admitted that Leosa who was his girl at the time, was very interested in the Pathfinder Project. Leosa left him after the hologram was stolen. She was brought in for questioning, and she denied any wrong doing. Deanna Troi who was present during the questioning, knew she was lying. Leosa admitted that she was not a teacher and she admitted her participation in the crime and identified the Ferengi involved in the theft.(VOY: "Inside Man")

Leosa was played by actress Sharisse Baker-Bernard.
