The latest student facing criminal charges, Zakari Hart, attends Pinkston High School in Dallas.

The 17-year-old allegedly posted on social media that a clown was planning to bomb his school.

But some students said Hart’s post was just a prank… a prank that could land Hart a year or more in jail.

“When those threats go out, we have parents who say ‘I’m not sending my child to school,’ we have children who are fearful while at school, administrators fearful and they’re looking for us to do our job,” said Dallas ISD Police Chief Craig Miller.

Hart’s arrest is the second one this week.

A Rockwall ISD student is also accused of making a terroristic threat.

Three other DISD students faced terror threat accusations in the spring semester.
