Kentucky State Police say three people were arrested in connection to social media threats made toward Knox County Schools. Sunday afternoon, Kentucky State Police, Knox County Deputies and Barbourville Police have all worked on the investigation. State police said a 13-year-old girl who attends Knox County Middle School and an 16-year-old girl who attends Knox County Learning Academy came up with the idea to send out a social media threat in hopes of school being cancelled. Both juveniles were placed under arrest and taken to the Barbourville Police Department for questioning then taken to the Breathitt County Juvenile Detention Center for their charges. KSP said 19 year old Megan Scott of Corbin who attends Knox Central High School was also arrested for her involvement. Scott was aware of the threats and failed to notify authorities. She was charged with complicity to terroristic threatening and taken to the Knox County Detention Center. Troopers are still investigating the incident.
