52-year-old Kenneth Webster Enlow of Tulsa was reportedly caught after a woman and her 7-year-old daughter spotted him peering up at them from inside the toilet.
Firefighters had to hose down Enlow, who was "covered in human waste," before transporting him to a local hospital for evaluation.
However, the evaluation did not reveal injuries consist with his alibi.
While booking Enlow on Peeping Tom charges, deputies learned that the suspect had a felony warrant stemming from a 1998 embezzlement case as well as two prior convictions for public intoxication.
He remained in jail as of Monday afternoon. An arraignment date has been set for July 15.
