On May 10, 2012, the United States Department of Justice (DOJ) in "United States v. Maricopa County, et al" (Case number 2:12-cv-981), filed suit against Arpaio, the MCSO, and Maricopa County, alleging that "The Maricopa County Sheriff's Office (MCSO) and Sheriff Joseph M. Arpaio have engaged and continue to engage in a pattern or practice of unlawful discriminatory police conduct directed at Latinos in Maricopa County and jail practices that unlawfully discriminate against Latino prisoners with limited English language skills." The complaint included accusations that Arpaio and his staff forced women to sleep in their own menstrual blood, assaulted pregnant women, ignored rape, and criminalized being a Latino.
