The threat was made on social media.
Uvalde police have made an arrest after a student on social media made a shooting threat at Uvalde High School just five months after the May 24 mass shooting at Robb Elementary, where 19 students and two teachers were killed. The threat was reported by someone through the STOPit app, which allows people to report potential threats anonymously, according to an email message from the district and a Facebook post from Uvalde PD.
The Uvalde Police Department and Texas Department of Public Safety Troopers were made aware of the threat as the school district suspended its entire police force indefinitely. The DPS and local police identified the minor who allegedly made the threat and arrested him for the crime of threatening terrorism, according to the Facebook post.
