Officials from two different Central Texas schools are investigating after social media posts circulated Thursday and Friday about "clowns" making threats.

Friday morning, a student at Manor High School contacted KVUE with a screenshot of a Facebook thread that contained an alleged threat against the school. "Klown Joey," one of the users in the thread, wrote Thursday, "Where gonna get yall manor high kids in all the bathrooms we got cameras set up we are out to kill and attack ... see y'all tomorrow."

Kristen Dark with the Travis County Sheriff's Office said they were made aware of the post Thursday afternoon when an investigation was initiated. She said "at this point, there's no credibility to the post." She also said campus police at Manor High School "are aware and will be diligent in their duties today as always."

In a letter sent to Del Valle High School parents Friday morning, the principal said they "have been made aware of a rumor about clowns threatening the security" of the school. He said "we are cooperating with law enforcement and diligently investigating this rumor. School is continuing as usual today."

According to KVUE's sister station in Corpus Christi, school district police there are also on alert Friday after "clowns" posted on social media claiming they were planning on "visiting" 10 different schools. There was no outright threat made, but police are monitoring the schools.
