CHICAGO (AP) — Nearly 2 dozen illegal immigrants were arrested Wednesday, accused of using fake security badges to work in critical areas of O'Hare International Airport, including the tarmac, authorities said.

The 23 illegal workers were employed by Ideal Staffing Solutions Inc., whose corporate secretary and office manager also were arrested after an eight-month investigation that involved federal, state and Chicago authorities.

The company contracted work for carriers including United Airlines, KLM and Qantas, said Elissa A. Brown, a U.S. Immigration and Customs Enforcement agent.
