A raid targeting illegal immigration has led to the arrests of 21 Phoenix-area McDonald's workers, and authorities were still seeking 30 other employees as part of their investigation.
Those arrested during the raid of four McDonald's in three Arizona cities were being held on suspicion of identity theft.
Maricopa County Sheriff Joe Arpaio says it will take more time to determine whether any of them are illegal immigrants as officials suspect.
Deputies also searched a mansion in the tony Phoenix suburb of Paradise Valley. The mansion is owned by Richard Coulston, who owns the restaurants. Coulston was not arrested.
McDonald's Corp referred comment to Coulston's company, R&L Management. In a statement, the company says people shouldn't jump to conclusions without all the facts.
