A former Cobb County student is accused of using a social media app to post a rumor of a threat towards Harrison High School.

The former student is charged with one count of disruption of public schools, which is a misdemeanor, in connection with the message police say was posted on SnapChat sometime between Sept. 11-13.

According to an arrest warrant obtained Friday by Cobb County Schools police, the former student posted on SnapChat “don’t go to school tomorrow, if u know u know,” which cops said caused Harrison students “to be concerned for their safety.”

The alleged post caused a “public panic,” resulting in a large number of Harrison High School students not attending classes Friday because they were afraid a school shooting would take place, according to the warrant.

A Cobb County School District spokeswoman said talks of the alleged threat circulated Thursday and Friday.

“As was communicated by the principal and the district in multiple ways, police quickly investigated and determined that while the social media (post) was unsettling and disruptive, no threat to the school actually existed,” the school system said, adding the former student was arrested for “creating and spreading rumors.”

According to the warrant, the former student said “he wanted to ‘piss off’ his former classmates and scare them.” No additional details were provided by the school district.
