Magician David Copperfield has been accused of raping a woman in the Bahamas, reports claim.

Authorities in Seattle, where the alleged victim lives, are believed to have turned the case over to the FBI because she did not contact police until she returned to the US.

Investigators raided a warehouse belonging to Copperfield in Las Vegas on Thursday. According to local TV station KLAS, 12 agents seized a computer hard drive, a digital camera memory chip and £937,000 in cash from the property, which the 51-year-old has dubbed the "International Museum and Library of the Conjuring Arts".

FBI Agent Robbie Burroughs told Fox News: "The investigation is related to a Seattle case. The Seattle case is pending and that means we can't say anything about it."

Copperfield's lawyer David Chesnoff denied the rape claims, saying: "It is important these allegations be put into perspective. An unidentified woman has made serious allegations against David Copperfield.

"Although authorities have not revealed her identity to us, we know these allegations are false because David Copperfield has never forced himself on anyone."
