A Pennsylvania Middle School principal is back on the job after being busted in an undercover sex-sting.

Kim Sean Crummie, the principal of Valley Middle School in the New Kensington-Arnold School District, has been charged with sex crimes.

According to police, Crummie met with the undercover officer in the men’s bathroom at Harrison Park in Harrison Township.

It was there that Crummie allegedly made his indecent proposal to the officer.

Parents with children in Valley Middle are appalled.

“That doesn’t sit well with me at all, not one bit,” said father Greg Pesanski.

Crummie was arrested and released from police custody last Friday.

He returned to his principal job earlier this week.

A decision about his immediate future could come from the school district today.
