U.S. Immigration and Customs Enforcement says a Maine police officer arrested by immigration authorities has agreed to voluntarily leave the country.

ICE arrested Old Orchard Beach Police Department reserve Officer Jon Luke Evans, of Jamaica, on July 25, as part of the agency’s effort to step up immigration enforcement. Officials with the town and police department have said federal authorities previously told them Evans was legally authorized to work in the U.S.

Evans’ arrest touched off a dispute between Old Orchard Beach officials and ICE. Police Chief Elise Chard has said the department was notified by federal officials that Evans was legally permitted to work in the country, and that the town submitted information via the Department of Homeland Security’s E-Verify program prior to Evans’ employment. Assistant Secretary of Homeland Security Tricia McLaughlin then accused the town of “reckless reliance” on the department’s E-Verify program.
