FBI agents served the complaint from the U.S. Securities and Exchange Commission on Texas billionaire Allen Stanford in Virginia, an FBI spokesman said on Thursday.

FBI spokesman Richard Kolko said the FBI acted at the request of the SEC and that Stanford had not been arrested. The complaint, accusing Stanford of an $8 billion fraud, was served on him by agents from the FBI's office in Richmond, Virginia. Kolko said.
