St. Louis (KSDK) -- A St. Louis man is accused of transporting a 16-year-old girl across state lines to make her work as a prostitute.
The U.S. Attorney of the Eastern District of Missouri said Reginald Williams was charged with interstate transportation of a minor with the intent to engage in prostitution.
The FBI and St. Louis County police officers arrested Williams Friday.
Williams is accused of posting an online ad featuring pictures of the girl and offering her services for commercial sex. Detectives reviewed the ad and traced the phone number associated with it to Williams, according to the affidavit filed with the criminal complaint.
The ad listed her age as 20, but Illinois police confirmed she was born in 1996.
An undercover detective called the number listed in the ad to set up a paid sex date. Officers went to the hotel and found two minor girls and Williams.
The U.S. Attorney said Williams transported the 16-year-old girl to the St. Louis area and Chicago.
If convicted, Williams could face 10 years to life in prison.
