HOUSTON (KIAH) — Houston-area school districts are reacting to a viral TikTok trend encouraging students to bring weapons to school on Friday, Dec. 17 to “every school in the USA, even elementary.”

The viral post has circulated nationally, calls students to commit acts of violence unofficially marking Dec. 17 as ‘National Shoot Up Your School Day.’

While the post does not target any specific schools, school systems across the nation are taking precautions and being hypervigilant to any potential threats.

Several school districts in the Houston area have banned backpacks from being brought to school on Friday. The list includes:

Alief ISD

Cy-Fair ISD

Channelview ISD

Conroe ISD

Fort Bend ISD

Katy ISD

Lamar CISD

La Porte ISD

Royal ISD

Spring ISD

Waller ISD

HISD said that individual schools in its district will make the decision to allow backpacks on Friday.

Other school districts, including Klein ISD, will allow students to bring their backpacks to campus, but are monitoring any possible threats made to their schools.

“The Klein ISD Police Department continues to investigate whether there are any local connections to these social media posts. At this time, Klein ISD Police have not acquired any evidence that would deem these threats as credible in our district. 

“Families, please talk to your children about the serious nature of making threats. Serious legal repercussions exist for making threats, even if they are posted as a prank or joke. Klein ISD takes these hoaxes very seriously and will work to prosecute perpetrators to the fullest extent of the law.”

David Kimberly, Klein ISD Chief of Police

TikTok responded to the unnerving trend in a tweet saying they are working with law enforcement to investigate potential violence.

If anyone has information on a potential threat, they are asked to notify a staff member or local authorities immediately.
