Federal authorities have ended a two-year investigation into rape allegations made against David Copperfield and will not be pressing charges against him.

Looks like their case was just smoke and mirrors.

The 21-year-old woman who accused the Las Vegas-based illusionist of making her panties disappear and sexually assaulting her also filed a civil suit.

She told investigators that Copperfield invited her to his private island in the Bahamas after meeting her after a show in Kennewick, Wash., in 2007.

He attacked her when she visited, the plaintiff claimed.

No charges will be pressed against David Copperfield.

Copperfield denied any wrongdoing throughout and called the suit purely "extortion for money, plain and simple." Looks like the feds ultimately agreed.

A judge granted David a six-month delay in October while authorities wrapped up their investigation. So now it's time for the plaintiff to make a move.

That move had better be a good one. This man once made a train car disappear. You think he can't get out from under a little lawsuit? Seriously?
