WICHITA, Kan. (AP) — A Wichita, Kansas, owner of a massage parlor has pleaded guilty to federal charges related to a sex-trafficking case involving a Chinese woman.

Prosecutors say 60-year-old GiGi’s Elite Massage owner Samir Elias pleaded guilty in federal court Monday in Wichita to one count each of harboring an alien for financial gain and of importation of an alien for prostitution.

Prosecutors said Elias was housing a Chinese woman who worked at his massage parlor, knowing she was selling sex at the business. Elias admitted collecting from her money he knew were proceeds from that activity.

Prosecutors say the woman was arrested after offering sex acts to an undercover police detective who went into Elias’ parlor for a massage.

Elias’ sentencing is scheduled for Dec. 12.
