CHESTERTOWN - An 18-year-old female student at North Warren High School was arrested after she allegedly spiked a teacher's coffee with a chemical, police said this week.
Sierra C. Heller of Panther Mountain Drive in Chestertown was charged with third-degree assault, a misdemeanor, following an investigation by the Warren County Sheriff's Office.
Police said that on May 13, Heller put Expo cleaner, a chemical used for cleaning dry-erase boards into the coffee of Eric Bott, a mathematics teacher, and he then unknowingly drank some of it.
Bott was treated at the Chestertown Health Center, where he was treated for irritation of the throat and released.
County Undersheriff Robert Swan said the Sheriff's office wouldn't be releasing more information about the incident, except that Heller claimed it was accidental.
Heller was arraigned in the town of Chester court and she was due to return to court Tuesday to answer the charge.
Town Court Clerk Karen Griffen didn't disclose any details on the case Tuesday afternoon. Officials said Heller was being treated as a juvenile offender and the details would not be made public.
Sheriff's Investigator John Maday and Patrol Officer Robert Gould handled the case.
