NORCO – A woman was behind bars Saturday, accused of telling people there was a bomb in her car at a Department of Motor Vehicles office in Norco, Riverside County sheriff's officials said.

The woman's arrest occurred Friday, the same day thousands of DMV customers endured longer lines at locations across the state after employee layoffs were imposed by Gov. Arnold Schwarzenegger.

Crystal Kay McPhee, 57, was arrested about 2:30 p.m. Friday after deputies went to the Norco DMV office at 3201 Horseless Carriage Drive in response to a bomb threat report, according to jail records and a sheriff's sergeant.

The DMV office building and parking lot were evacuated while deputies waited for a hazardous device team to arrive, sheriff's officials said.

Hazardous device deputies examined the vehicle in question and found no bomb or explosive materials. McPhee, who allegedly told DMV employees she had a bomb in the vehicle and not to touch it, was arrested on suspicion of making a criminal threat.

McPhee was held today at Robert Presley Detention Center in Riverside on $207,500 bail, according to a jail spokeswoman and jail records. She has a court appearance at 8 a.m. Tuesday in Riverside Superior Court.

Details of whether McPhee was a DMV customer or whether she had any working ties to DMV were not available.

The alleged threat and arrest came on the same day DMV customers endured long lines at some locations across the state due to layoffs ordered by Schwarzenegger.

In response to the governor's order, the DMV dismissed 700 employees statewide, roughly 8 percent of its workforce. DMV Director George Valverde told The Los Angeles Times the layoffs were “putting a strain” on remaining employees.

A state workers union on Friday filed a lawsuit to reverse more than 10,000 layoffs ordered by Schwarzenegger. They also filed a complaint to block the governor's move to temporarily cut most of the state's 200,000 employees' salaries to the federal minimum wage of $6.55 an hour.
