The spouse of an active-duty Coast Guardsman was arrested this week by federal immigration enforcement inside the family residential section of the U.S. Naval Air Station in Key West, Florida.

“The spouse is not a member of the Coast Guard and was detained by Homeland Security Investigations pursuant to a lawful removal order,” said Coast Guard spokesman Lt. Cmdr. Steve Roth in a statement confirming Thursday’s arrest. “The Coast Guard works closely with HSI and others to enforce federal laws, including on immigration.”
