The U.S. Justice Department has launched a civil-rights investigation of the Maricopa County Sheriff's Office after months of mounting complaints that deputies are discriminating in their enforcement of federal immigration laws.

Officials from the Justice Department's Civil Rights Division notified Sheriff Joe Arpaio on Tuesday that they had begun the investigation, which will focus on whether deputies are engaging in "patterns or practices of discriminatory police practices and unconstitutional searches and seizures."

An expert said it is the department's first civil-rights probe related to immigration enforcement.
