SHARON, Vt. — Vermont State Police say the principal of the South Royalton School has been arrested on charges of videotaping a girl in the bathroom of his home.

WCAX-TV reports that 55-year-old old Dean Stearns of Sharon pleaded not guilty on Thursday to charges of voyeurism and child pornography.

Police arrested Stearns after they say a 16-year-old girl temporarily staying at his home called police on Wednesday night to say she believed she was being videotaped at the home.

Police say the investigation showed that she was being recorded in the bathroom.

Police say there’s no evidence of other victims but the investigation is continuing.

The school supervisory union says Stearns has been placed on administrative leave.
