"Knock that crap off." That's the message Clay County Sheriff Darryl Daniels is sending to students Friday following the increase in school threats on social media.

On Friday, two students were arrested over two separate school threats: One student was a 15-year-old girl attending Oakleaf High School and the other a 13-year-old girl attending Oakleaf Junior High.

"It's not cute, children, to make these types of posts," Daniels said during a press conference Friday night. "There's more serious things going on ... more serious crimes going on ... that really need the attention of law enforcement."

Daniels said he held the press conference to help emphasize the severity of making such threats. He said students, no matter the age, could be arrested and could face a second-degree felony. He said they could face up to 15 years in prison.

"These are teenage kids going down a path, being silly like kids are, and doing things that we call stupid as adults and they're messing up their lives," he said.

He also hopes that parents will stress to their kids to "knock that crap off."

"What you're going to do is get your behind in trouble and wind up in jail, just like your two little partners did ... and you bring embarrassment to your families ... to your classmates," he said. " ... Knock it off."

Regarding the recent arrest of the 13-year-old, Daniels said the girl tried to cover her tracks. He said she reported the post, but after investigating, deputies discovered that she made the threatening post.
