A 10-year-old Florida student has been arrested after making a school threat, sheriff's officials said.
Investigators learned of the threats made by the boy on Saturday and arrested him, Lee County Sheriff Carmine Marceno said in a social media post.
"This student's behaviour is sickening, especially after the recent tragedy in Uvalde, Texas," the sheriff said.
An 18-year-old gunman entered Robb Elementary School in Uvalde, Texas, on Tuesday and opened fire on a fourth grade classroom, killing 19 students and two teachers.
Marceno said that making sure "our children are safe is paramount."
