A Westmoreland County middle school principal was charged this week with indecent exposure and open lewdness, according to court documents.

Allegheny County police filed charges Tuesday against Kim Sean Crummie, 51, for an incident that occurred Friday in a public park in Harrison.

Mr. Crummie, of Sheffield Street on Pittsburgh's North Side, is principal of Valley Middle School in the New Kensington-Arnold School District, according to the district's Web site.

According to a police affidavit, an undercover officer was propositioned in a restroom at Harrison Hills Park at 11:14 a.m. last Friday.

The officer said Mr. Crummie exposed and manipulated his genitalia, and he offered to perform multiple sex acts.

After Mr. Crummie produced a jar of Vaseline, the officer identified himself and placed the suspect under arrest, the affidavit said.

Charges of indecent exposure and open lewdness were filed on Tuesday.

A preliminary hearing is scheduled June 4 before District Judge Carolyn S. Bengel in Natrona.
