Maricopa County Sheriff's deputies have arrested four people at a Phoenix workplace for allegedly using false identification.
Sheriff Joe Arpaio said his office received a tip from an ex-employee that several of the workers at Sonoran Doors might be using fake IDs.
After a search of employment records, deputies say they determined that some of the 20 employees at the business were using false identification to gain employment there.
The business manufactures various kinds of specialty doors for sale. Officials at Sonoran Doors didn't immediately return a call for comment on the employee arrests Wednesday.
The sheriff's office says the criminal workplace raid was the 64th such operation since 2008.
Arpaio says 631 suspects arrested in the raids were illegal immigrants and 80 percent of them were charged with identity theft.
Reports about President Obama's "Deferred Action Program" that will allow as many as 1.75 million young illegal immigrants to live and work in the U.S., suggested Wednesday that the federal government may be concerned about the potential of fraud as they administer the program, MCSO said.
"Officials overseeing this new program have cause for concern," Arpaio said. "Identity theft is a huge problem in the workplace. Mark my words. Someone will figure out how to manipulate the new deferred action program to his or her benefit."
