OMAHA, Neb. (AP) — Three years after it was filed, a lawsuit filed by a Papillion man who says he was unlawfully detained and wrongly treated as an illegal immigrant has been dismissed against Sarpy County.

U.S. District Judge Joseph Bataillon dismissed the lawsuit against the Sarpy County sheriff, jail staff and a federal immigration agent on Thursday. The American Civil Liberties Union of Nebraska had sued on behalf of Ramon Mendoza in 2013.

Bataillon said the lawsuit failed to show Mendoza’s constitutional rights were violated.

Mendoza was jailed in March 2010 after he was pulled over by a sheriff’s deputy for a traffic infraction.

Mendoza is a naturalized U.S. citizen from Mexico, but was held for days on suspicion of being in the country illegally.
