The American Civil Liberties Union's Arizona affiliate has filed a legal claim against the Tucson Police Department over the Oct. 8 detention of two immigrants during a traffic stop.
The claim, a precursor to a possible lawsuit, demands $250,000 for each man and alleges the detention violated their constitutional rights, including protections against unreasonable seizures.
City Attorney Mike Rankin did not immediately respond to a request for comment, but Police Chief Roberto Villaseñor has said officers must notify the Border Patrol when immigrants cannot produce legal ID.
Police said they pulled over a car because it had no license plate light.
The detentions prompted a protest during which police used pepper spray to disperse the crowd.
