The wife of an active-duty Coast Guardsman was arrested earlier this week by federal immigration authorities inside the family residential section of the U.S. Naval Air Station at Key West, Florida, after she was flagged in a routine security check, officials said Saturday. “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 spokesperson Lt. Cmdr. Steve Roth in a statement confirming Thursday’s on-base arrest. “The Coast Guard works closely with HSI and others to enforce federal laws, including on immigration.”
