Three women were arrested during a prostitution sting at a spa in suburban Willowbrook on Friday, authorities said.
Detectives conducted an undercover investigation at Pine Tree Spa, located at 10S648 Route 83, according to the DuPage County Sheriff's Office.
The operation resulted in the arrests of three women: Ho K. Lee, 38, Mi H. Saito, 51, and Hyojin Yoo, 44, officials said.
