David Copperfield's performance in Malaysia this month has been cancelled after the FBI launched an investigation into the world-famous US magician and illusionist, a report said Monday.

The organisers of his two-day stint here on October 30 and 31 said the decision to cancel was made after agents from the Federal Bureau of Investigations raided Copperfield's storage warehouse in Los Angeles last week.

"He needs to help in the investigations. Copperfield is not prevented from leaving the United States but he needs time to get to the bottom of things," Arianna Teoh, director of Arianna Event Management, said in The Star newspaper.

FBI agents took away a computer hard drive, digital camera memory chip and seized nearly two million dollars in cash during the raid last Wednesday.

They also visited the MGM-Grand Hotel and Casino on the Vegas Strip, where Copperfield often performs.

The FBI has not revealed the purpose of the raid and David Chesnoff, lawyer for the 51-year old magician, issued only a brief statement.

"We understand there is an investigation, we are in touch with the investigators, and are respecting the confidentiality of the investigation," Chesnoff said.

Teoh said Copperfield's performance could still take place later.

"The people here and all his fans have been very supportive of him and if he is cleared, then it is possible that he will still continue with the show," she said.
