A teenage girl has been charged in connection with a false fire alarm that led to an injury during the brief evacuation of students from South Hagerstown High School Monday .
Hagerstown Fire Marshal John Hersh said a student who was on crutches fell while leaving the building and was injured again.
For that reason, the 15-year-old girl has been charged with reckless endangerment in addition to pulling a false fire alarm, Hersh said.
The alarm in a hallway at the school was pulled manually at 11:40 a.m., Hersh said. His investigation and questioning of witnesses led to the charges.
