U.S. authorities arrested 25 illegal immigrants at the Barksdale Air Force Base, in Louisiana, on Friday, media reports said Saturday.
The contract workers were arrested by Immigration and Customs Enforcement agents, with collaboration from the Air Force.
The construction and landscaping workers' names were put on a list by the six companies doing business on the base, Frank Hartnett, a spokesman for 2nd Bomb Wing based at the airport, was quoted as saying.
A news release by the 2nd Bomb Wing said the workers were "foreign nationals" but did not specify a country of origin, the reports said.
The majority of the workers had obtained fraudulent Social Security and alien registration numbers to complete forms, the release was cited as saying.
The Barksdale Air Force Base, home for the Air Force's 2nd Bomb Wing, also provides global combat capability and trains all B-52 combat crews.
