A construction contract worker at a nuclear power plant west of Phoenix has been arrested for trying to enter the facility with a fake identification card.
Maricopa County Sheriff's officials say 32-year-old Cruz Loya Alvares was booked into jail on suspicion of criminal trespassing on a nuclear power plant.
Authorities say Alvares' access was limited to a part of the Palo Verde Nuclear Generating Station that doesn't contain any of the triple-reactor's vital controls.
A security guard prevented Alvares from entering the plant Tuesday after noticing his Mexican ID card was expired.
Authorities say Alvares returned Wednesday with an Arizona identification card that proved to be bogus.
Sheriff's officials say Alvares lives in Mesa but illegally entered the U.S. about 15 years ago. It's unclear whether Alvares has a lawyer.
