U.S. Park Police have identified a woman arrested for tying herself to a White House fence as actress Q'orianka (kohr-ee-AHN'-kuh) Kilcher.

Authorities say the 20-year-old tied herself to the fence Tuesday and her 41-year-old mother, Saskia, poured a black substance over her.

They told officials they were protesting a visit by the president of Peru. Q'orianka Kilcher's father is a Peruvian Indian.

Park Police spokesman Sgt. David Schlosser identified the mother, who's charged with defacing government property, and daughter, who's charged with disorderly conduct.

Kilcher's publicist Carlyne Grager confirmed the arrests and said the actress is a strong supporter of indigenous populations around the world.

Kilcher played Pocahontas in the 2005 film, "The New World."
