FBI agents Wednesday raided Copperfield's warehouse and a theater where he performs in Las Vegas, after a Seattle woman complained to the police that she was assaulted by Copperfield in the Bahamas, where he owns four islands.

The illusionist's lawyer, David Chesnoff, was quoted as saying: "The allegation is 100 percent false, and we deny it in the strongest possible terms. Unfortunately, false allegations are all too often made against famous individuals."

Copperfield's Las Vegas warehouse, known as the International Museum & Library of the Conjuring Arts, is where he stores tricks and memorabilia from around the world. A computer hard-drive and a memory chip from a digital camera were reportedly taken away.

The FBI is involved because the alleged crime occurred outside the United States, but did not specify the type of allegation made against Copperfield.

Copperfield, 51, performs in Las Vegas and around the world, has starred in TV specials, and was named a "living legend" by the Library of Congress.

He was once engaged to model Claudia Schiffer.
