An investigation at Chicago's O'Hare International Airport led to the arrest of two staffing firm internal employees and 23 workers on Wednesday, U.S. Immigration and Customs Enforcement reported. The probe found temporary workers employed through Bensenville IL-based Ideal Staffing Solutions Inc., fraudulently obtained airport security badges, allowing them to enter secure areas to load freight and meals for companies, including commercial airlines.

A review last month of security badge applications by Ideal Staffing for 120 of its workers found that 110 listed Social Security numbers were nonexistent or belonged to another person, ICE reported.

Mary Gurin, 36, corporate secretary of Ideal Staffing, and Norinye Benitez, 24, an office manager, face charges of harboring illegal aliens for financial gain and misuse of a Social Security number, according to ICE. The 23 workers face charges over the use of fraudulent security badges and face deportation. Twenty of the workers are from Mexico and two are from Guatemala.

Ideal Staffing workers were told they needed to have identification, but that the document did not need to be legitimate, ICE said. In one instance, a worker was given a box with 20 airport security badges and asked to pick one with a photo that looked most like him.

Gurin and Benitez, who is allegedly an illegal worker herself, each face up to 10 years in prison on the charges of harboring an illegal alien and five years for misuse of a social security number, according to ICE.
