WILLISON, Vt. — Police in Vermont say a 15-year-old student was cited after approaching a classroom wearing a clown mask and banging on the windows as clown sightings are viewed as potential public safety threats throughout the country.

Police say the student at the Howard Center’s Jean Garvin School in Williston was cited Wednesday as a juvenile on suspicion of disorderly conduct and false public alarm after he approached the classroom.

Officer Harley Pecor told the Burlington Free Press that one student ran out of the classroom in fear and the entire class was panicked.

The center’s website says the school has been serving the “therapeutic and academic needs” of students ages 12-16 since 1997.
