The Hamilton County Sheriff's Office said a 16-year-old student at Central High School brought a BB gun to school today.
A student alerted School Resource Officers this morning about a suspicious post they saw on social media, according to Matt Lea, spokesman for the Sheriff's Office.
When Central High School administrators and authorities questioned the student seen in the social media post the weapon was located within his belongings on school property, Lea said.
The male student was taken into custody and transported to the Hamilton County Juvenile Detention facility, charged with possessing a weapon on school property.
Lea said you cannot traditionally charge someone for bringing a weapon to school if it is BB gun, because they are not considered firearms. Someone can be charged though if the BB gun is being displayed in a manner that is threatening or causes alarm, he added.
"This incident met that criteria and an arrest was made," Lea said.
This is the third incident today at a Hamilton County school. A threat was found this morning in a bathroom at East Hamilton School, and East Ridge Middle School was evacuated for a bomb threat.
