The sheriff's office said the woman was at an Alexandria, Va., pool hall on Monday when she met a man who later offered to drive her home. She went into his car and found several other men inside. She was taken against her will to a Waldorf home where more than a dozen other people live, officials said.
A group of men, including one with a knife, forced her to perform various sexual acts and threatened to kill her, authorities said.
Tuesday morning, the woman escaped and ran to another home to get help.
Officers arrested and charged six men, ages 18 to 28, with first-degree rape and false imprisonment.
