School threats, related violence has increased in the week after the Antioch High School shooting, Nashville Police say.

Police said a male student shot two people at the high school on Wednesday morning before turning the gun on himself.

A 16-year-old female student was killed, another student was wounded, and the shooter—a 17-year-old male student—killed himself, per police.

The Metro Nashville Police Department opted to permanently add a third school resource officer to Antioch High School as students return Tuesday.

Two local students were arrested in unrelated cases for making school threats Thursday. In the first case, Dorrian Harp, an 18-year-old student at Hunters Lane High School, allegedly admitted to telling another student in his class on Tuesday that he would shoot up the school the next day.

Threats against schools and institutions are taken very seriously by the MNPD. Those responsible, once identified, will be prosecuted.”

On Wednesday, the Nashville Predators held a moment of silence to remember the victims of the Antioch High School shooting on Jan. 22.
