NEW YORK — A lawyer for a Russian diplomat's daughter accused of being a spy in New York says her father told her to go to police with a fake passport an undercover FBI agent gave her.

Attorney Robert Baum said Friday he may use that information to appeal a magistrate judge's decision to deny bail for his client, 28-year-old Anna Chapman.

Prosecutors say an FBI agent posing as a Russian consulate employee asked Chapman to deliver a fake passport to another spy.

Chapman was the first of 10 spy suspects arrested over the weekend in the United States to be denied bail. She faces a charge of conspiring to act as an unregistered agent of a foreign government, which carries a potential penalty of five years in prison.

Baum says his client remains in solitary confinement in Brooklyn.
