Two women were arrested on preliminary prostitution charges after a several months-long investigation into a Warsaw massage parlor.

Li-Lan Chu and Yi Li Liao were booked into the Kosciusko County Jail on Friday, July 8, according to the Warsaw Police Department.

Warsaw and Indiana State police served a search warrant at Ying Massage at 493 S. Circle Drive West, looking for evidence of corrupt business influence, tax evasion and prostitution.

Police are still investigating the alleged prostitution and tax evasion. Other arrests are expected. Chu and Liao are also expected to face charges beyond prostitution.

The Internal Revenue Service is helping police with the investigation.
