A cafeteria worker has been charged with threatening to use her oxygen tank to blow up the Pennsylvania public school where she worked.
The Butler Eagle reports that 52-year-old Kimberly McElravy, of Petrolia, is accused of making the threats Feb. 5.
Karns City School District Supt. Eric Ritzert said the threat was made to other employees outside the presence of schoolchildren. Ritzert said school wasn't disrupted and no students were endangered.
Online court records show state police have mailed misdemeanor charges of terroristic threats and harassment to McElravy, along with a citation for disorderly conduct.
McElravy declined to comment when reached at home Monday by The Associated Press. A preliminary hearing on the charges hasn't been scheduled.
McElravy remains on unpaid leave.
