(AP) — Authorities have charged a Fort Hood sergeant with paying for sex with a soldier in a prostitution scheme allegedly arranged by a coordinator of the Texas Army post’s sexual assault prevention program.

Master Sgt. Brad Grimes was charged in military court Wednesday with patronizing a prostitute, conspiring with another soldier to patronize a prostitute, committing adultery and solicitation to commit adultery.

The woman soldier hasn’t been charged.

Fort Hood spokesman Chris Haug says the charges stem from an investigation of a lower-level coordinator of Fort Hood’s sexual assault and harassment prevention program.

In May, the Army said that coordinator is accused of sexual assault and possibly arranging for at least one woman to have sex for money. That soldier is a sergeant first class who hasn’t been charged
