The American Civil Liberties Union has sued the Border Patrol's parent agency for records on its activities away from the nation's border with Mexico.

The lawsuit filed Tuesday in federal court in San Diego seeks records on the agency's so-called "roving patrols" in the San Diego and El Centro sectors in Southern California. The plaintiffs say agents work a considerable distance from the border with Mexico and have reportedly stopped farm workers and residents for questioning in Fallbrook, about 70 miles north of Mexico, and Laguna Beach, about 90 miles north.

The lawsuit names the Department of Homeland Security and its Customs and Border Protection unit, which includes the Border Patrol. It says the agencies haven't produced records requested under the Freedom of Information Act.

CBP had no immediate comment.
