Authorities in Charlotte, N.C., arrested a 16-year-old high school student after a teacher discovered an alleged threat he reportedly wrote on a calculator.
Charlotte-Mecklenburg police said they arrested the Olympic High School student Thursday, after he used the calculator to write that "a Sandy Hook would happen at the school," CBS local affiliate WBTV reports.
The teen is being charged with the felony crime of falsely reporting mass violence against an educational property, along with a misdemeanor of communicating threats.
Authorities who searched the school grounds said they found no risks of danger, NBC local TV station WCNC reports. However, distressed parents of students at the school pulled their pupils from classes Friday morning, after learning of the alleged copycat threat, according to CBS Charlotte.
According to WSOC TV, the teen is expected to appear in court Friday afternoon.
Following the Dec. 14 mass shooting at Sandy Hook Elementary School in Newtown, Conn., a slew of schools nationwide have faced similar threats. Authorities in each state reacted strongly to such threats, taking suspected parties into custody and often making an arrest.
