NATIONAL NEWS (CNN) — Five weeks after 12-year-old Rebecca Sedwick jumped to her death -- prompted, authorities say, by intense bullying -- police in Polk County, Florida, have arrested two girls on aggravated stalking charges.
Deputies arrested the girls Monday night and released them back to the custody of their parents, according to sheriff's office spokeswoman Carrie Eleazor.
No court date has been set, she said. It will be up to prosecutors to decide whether the girls will face any additional charges.
Authorities didn't release details of the accusations against the girls. But investigators have said previously that Sedwick faced intense bullying in school and online. The online bullying continued even after her mother pulled her out of classes, according to authorities.
Among the messages, according to the sheriff's office: "You should die" and "why don't you go kill yourself."
The night before Rebecca killed herself, authorities say she messaged a boy she had befriended online, writing, "I'm jumping. I can't take it anymore."
"Some of the juveniles have told us that Rebecca was absolutely terrorized on social media by some girls," Sheriff Grady Judd told reporters last month.
"She appeared to be beat down," he said.
