Silburne

Silburne was a thief who worked for the Boss. As part of the Boss' plan to frame Superman, Silburne wore an outfit identical to that of the Man of Steel, committing all manner of robberies. Silburne encountered the real Superman while casing the opera house, and, cornered, quickly confessed everything.

Superman then made Silburne take him to the Boss' mansion outside of town, where the Boss had a few of his own surprises in store for the hero. When Superman was briefly incapacitated by being dropped through a trapdoor, Silburne attempted to escape with the Boss but was quickly chased down and apprehended by the Man of Steel.
