The ACLU of Arizona has filed another legal claim against the Tucson Police Department in its ongoing battle against the department's enforcement of SB1070, also known to some as the "show me your papers" law.

The organization first filed a notice of claim in April.

It filed another challenge on Tuesday claiming Tucson police had unlawfully detained a man who was pulled over during a traffic stop and then turned over to U.S. Border Patrol. The man was cited for driving with a suspended license.

The organization said SB1070 leads to racial profiling. ACLU attorneys came to an agreement with the city of South Tucson after also filing a legal claim against the city. That agreement overhauled how South Tucson police deal with immigration checks and created a new database that will closely track encounters.
