Pinellas sheriff's detectives say a Clearwater woman informed the sheriff's office that her 17-year-old daughter had been threatened during Facebook Live video.
Investigators say another 17-year-old girl posted the video, threatening to shoot the victim while holding up what looked like an AR-15 style rifle.
The victim told deputies she had been bullied at Bayside High School where the two girls are students. The teenaged suspect was taken into custody at her St. Pete home where detectives determined she has no access to weapons.
She's been charged with threatening to kill or do bodily harm.
