SPRINGFIELD, Mo. (AP) — A third-grade public school teacher in Springfield has been placed on leave after being arrested in a prostitution sting.

The southwest Missouri school district says the woman has taught in the district since 2001. She was arrested last month along with her husband and two other women.

No charges have been filed, and Greene County prosecutors said Thursday they’re still investigating.

One of the women told an undercover officer that a man and woman rented the rooms and arranged the encounters through a website.
