RALEIGH, N.C. (AP) -- The U.S. Department of Homeland Security is investigating complaints that immigration detainees have been mistreated at the Wake County jail in Raleigh.
The agency's civil rights chief sent a letter last month announcing the probe to the North Carolina chapter of the American Civil Liberties Union. The ACLU had coordinated a group of 57 complaints from people detained at the jail in 2009 and 2010.
The complaints include allegations that people were called racial slurs, not informed of their rights and forced to sign their names to documents.
The Homeland Security Department oversees a program in which participating law enforcement agencies assist the federal government on immigration policies.
Wake County Sheriff's spokeswoman Phyllis Stephens says the department is waiting to be formally notified of the investigation before responding.
