HANOVER PARK, Ill. (WLS) – United States Immigration and Customs Enforcement agents arrested a police officer Thursday morning in Hanover Park, accusing him of being an unlawful immigrant from Montenegro.

Hanover Park police are now saying the department hired the officer in January in “full compliance with federal and state law,” adding, the village confirmed he was legally authorized by the federal government to work in the United States. That is contradicting what the Department of Homeland Security said earlier Thursday.
