FORT MYERS, Fla. (AP) – Sheriff’s deputies in Florida have arrested a 10-year-old fifth grade student accused of threatening to shoot up a school. Investigators learned of the threats made by the boy on Saturday and arrested him.

In a social media post, Lee County Sheriff Carmine Marceno called the student’s behavior “sickening, especially after the recent tragedy in Uvalde, Texas.”

An 18-year-old gunman entered Robb Elementary School in Uvalde on Tuesday and opened fire on a fourth grade classroom, killing 19 students and two teachers.

The Florida sheriff said making sure “our children are safe is paramount.”

They learned of the threatening text message on Saturday and arrested the boy.
