Washington ? The elder daughter of former Chilean dictator Gen. Augusto Pinochet requested asylum in the United States on Wednesday after being taken into custody at Dulles International Airport, Chilean and U.S. officials said.

Lucia Pinochet was taken into custody by customs officials because of an outstanding arrest warrant in Chile, officials said.

Chilean Interior Minister Francisco Vidal said U.S. Ambassador Craig Kelly had informed his government of the asylum request. A State Department official confirmed the request and said she will be interviewed by an asylum officer as early as today. The official spoke on condition of anonymity because he was not authorized to disclose the information.

Lucia Pinochet had been indicted by a Chilean judge on tax evasion and false passport charges, Chilean and U.S. officials said.

She was taken into custody after she got off a plane from Argentina that landed at Dulles International Airport, outside Washington, around 6 a.m. CST.

“We are interviewing her,” said Suzanne Trevino, a spokeswoman for U.S. Customs and Border Protection. While Pinochet was being detained, she was not under arrest.

Under normal procedures, a person who tries to enter the U.S. and is detained by customs is entitled to an admissibility interview.

Lucia Pinochet and several members of her family are implicated in a scandal involving the now-defunct Riggs Bank of Washington. The bank provided diplomatic banking services for decades until a Senate investigation found irregularities in its operations.

Investigators say the defendants together evaded $2.05 million in taxes.
