Five people in Miami were arrested for allegedly impersonating IRS agents in a telephone scam that defrauded more than 1,000 people and netted them about $2 million, a top Treasury Department official said Tuesday. J. Russell George, treasury inspector general for tax administration, said the alleged scammers demanded their victims wire them money immediately for apparent overdue taxes, according to the Associated Press. Those who were arrested are Jennifer Valerino Nunez, Dennis Delgado Caballero, Arnoldo Perez Mirabal, Yaritza Espinosa Diaz, and Roberto Fontanella Caballero.
