Unidentified bounty hunter (Imperial tip)

Six, months after the Battle of Yavin, an unsavory bounty hunter gave a tip to the Imperials. The tip led the Imperials to launch an attack on Mos Eisley spaceport, in order to root out their target, Luke Skywalker.

Behind the scenes
The bounty hunter was mentioned in the Official Nintendo Player's Guide for the 1998 video game, Star Wars: Rogue Squadron.
