Police in New Jersey said a "mystery pooper" responsible for repeatedly leaving human feces on a high school's field was identified -- as a nearby school superintendent.

The Holmdel Township Police Department said Holmdel High School staff were finding fresh piles of poop on a daily basis in the area surrounding the facility's football and track fields.

The school resource officer and school staff monitored the area and identified the "mystery pooper" as Thomas Tramaglini, 42, of Matawan.

Tramaglini is the superintendent of the Kenilworth School District, which does not include Holmdel High School, officials said.

"We learned of municipal court charges facing our current superintendent of schools in Holmdel, N.J.," the board said in a statement. "Given the nature of those charges, he asked for and was granted a paid leave of absence."

The district said Director of Academics Brian Luciani will step in for Tramaglini, who has served as superintendent since 2015.

Tramaglini faces charges of defecating in public, lewdness and littering, police said.
