Andiola and two others were arrested late Tuesday as police cleared out protesters camped outside U.S. Immigration and Customs Enforcement headquarters in Phoenix for more than a week, the (Phoenix) Arizona Republic said Wednesday.
Police Sgt. Trent Crump said officers warned demonstrators throughout the day their tents were on private property, and they would be arrested if they did not leave.
The demonstrations and the encampment were to call attention to the federal government's deportation policies.
Andiola and her two colleagues were among a group of six fasting since Feb. 22, as they seek the release of family members held at an ICE detention facility in Arizona, KTVK-TV, Phoenix, reported.
The three were arrested for violating an anti-urban camping ordinance.
