On Tuesday, Jan. 8, a joint investigation between the Lake County Sheriff's Office and Libertyville Police Department resulted in the arrest of Hong Yang, 41, of the 300 block of Cermak Road in Chicago.

The month-long investigation began after law enforcement received an anonymous tip that the Dragon Spa, located at 402 Peterson Road in Libertyville, was offering sex acts for money.

Three detectives received hour-long massages. On Jan. 8 around 1:00 p.m., Yang offered to massage one of the detectives' genital area for an additional fee. With the assistance of Libertyville Police Department, Lake County Sheriff arrested Yang.
