The mystery of a public pooper has been solved after police arrested a US school boss.
Holmdel High School students and staff were regularly making disturbing discoveries - human faeces spread around the track and football field.
In desperation, they called on police to launch an investigation.
"(The) Holmdel School Resource Officer was alerted by Holmdel High School staff and coaches that they were finding human feces, on or near the area of the High School track/football field on a daily basis," Holmdel police said in a statement on social media.
And this week, they caught the culprit - but it wasn't who they thought it would be.
Their school leader, Kenilworth Public Schools Superintendent Thomas Tramaglini was arrested by Holmdel police after he was seen defecating on the football field.
Tramaglini has been charged with public urination or defecation, discarding and dumping of litter, and lewdness, a Holmdel police spokesman says.
"Earlier today, we learned of municipal court charges facing our current superintendent of schools in Holmdel, NJ," Kenilworth Public Schools says on Facebook.
"Given the nature of those charges, he asked for and was granted a paid leave of absence."
Tramaglini will appear in the Holmdel Municipal Court on May 7.
