An assistant to the CEO of a Puerto Rico bank has been arrested on charges of perjury and obstruction of justice.

Nancy Velez is accused of making false statements while testifying before a grand jury. She had worked as a senior executive assistant at Doral Bank.

U.S. Attorney Rosa Emilia Rodriguez said Friday that Velez is accused of hiding information from FBI investigators probing alleged bank fraud, embezzlement and money laundering.

The indictment comes almost a year after the FBI raided Doral Bank's headquarters. The institution has since been taken over by another bank.
