(NEXSTAR) – Law enforcement and schools across the metro, and the country, are on high alert amid an apparent TikTok trend threatening violence nationwide on Friday. 

Authorities and school administrators in several states say they have been made aware of a social media challenge encouraging students to bring weapons to school on Dec. 17. So far, police departments and school districts are calling the threat unfounded. 

Kansas City police acknowledged the trend, but also said they do not have any specific about a threat directed toward a metro school.

The Shawnee Mission School District is one of several in the metro that emailed parents and guardians of students Thursday warning of the “National Shoot Up Your School Day” TikTok trend. The posts to TikTok and other social media platforms have not originated in Kansas City and do not refer to specific schools but are instead part of a “nationwide trend.”

The Olathe School District also warned families and asked parents and guardians to take to children about the situation.

“This is a great opportunity to talk with your children about the appropriate use of social media. and about the serious consequences of making any kind of threat,” the district said in a statement.

Clay County has extra sheriff’s deputies in and around schools on Friday, too.

TikTok released a statement Thursday which reads, “We handle even rumored threats with utmost seriousness, which is why we’re working with law enforcement to look into warnings about potential violence at schools even though we have not found evidence of such threats originating or spreading via TikTok.”

“Unfortunately, we’ve seen a trend of reposting messages that have no relation to our city, area or schools and many of the threats end up being hoaxes. Please take this time to talk to your child about being responsible on social media and not sharing these threats or warnings, even as a precaution,” Chief Ashley Gonzalez with the Austin Independent School District Police Department wrote in a Thursday statement.

Other districts and law enforcement agencies are also encouraging parents to talk to their children about the threats. It can be a difficult conversation, but the American Psychological Association offers a few tips on how to go about it. 

First, they suggest leading with listening. You may want to start out by asking your child what they’ve heard about what’s going on at school. You should answer your children’s questions honestly, suggests the APA, while making sure they know they are safe. 

“Parents should acknowledge to children that bad things do happen, but also reassure them with the information that many people are working to keep them safe, including their parents, teachers and local police,” says the APA. 

If your child has any information on a threat, be sure to share that information with law enforcement. In many cases, that can be done anonymously. 

Finally, the APA tells parents to keep an eye out for warning signs their kids may need additional help. 

“Such indicators could be a change in the child’s school performance, changes in relationships with peers and teachers, excessive worry, school refusal, sleeplessness, nightmares, headaches or stomachaches, or loss of interest in activities that the child used to enjoy.”

Making false threats of terrorism is a crime that can carry long prison sentences in many states. Parents may want to emphasize the consequences of spreading such rumors with their children. 

As a precaution, some schools like Gilroy High School in California have canceled classes for Friday. Others like Academy District 20 in Colorado Springs and Granite High School in Salt Lake City will have an increased police presence during the day, according to local reports.
