The Hamilton County Sheriff's Department says a student at Lookout Valley High School sprayed pepper spray in the hallway today just before 12:30. They say there was "limited" exposure to students and teachers. SRO Jamie Fields arrested a female student and charged her with Reckless Endangerment and Disruption of a lawful meeting. The student has not been identified. She was taken to the Hamilton County Juvenile Detention Center. The Fire Department was called and used fans to clear the air and checked that it was safe for students and teachers to enter the affected area.
