Q2 reports that the 35-year-old man accused of operating a prostitution ring involving minors is now facing additional charges related to promoting prostitution in Billings and Missoula.

Terrance Edwards was arraigned Tuesday in U.S. District Court in Billings on a new 11-count indictment. He’s now charged with sex trafficking by force, transportation of a minor with intent to engage in prostitution, obstruction of a sex trafficking investigation, tampering with a witness, transportation of a person with intent to engage in sexual activity, and distribution of marijuana to an individual under the age of 21. The charges stem from crimes that took place from April of 2016 to March 2017. At least six victims, including three under the age of 18, are listed in the charges.

Prosecutors allege Edwards operated sex trafficking operations in Montana, Utah and Washington state.
