A Cherokee County teenager was arrested Tuesday for allegedly bringing a gun to school.

School system police arrested the Creekview High School freshman on one charge of possession of weapon on school grounds, according to Barbara Jacoby, district spokeswoman. The 16-year-old, whose name was not released, was transported to a youth detention center, Jacoby said.

A parent at the school alerted police that the weapon was on campus Monday, according to a letter Principal Adrian Thomason sent to parents Tuesday.

“After speaking with all parties involved, we have determined that a student did indeed have a small caliber weapon on school grounds during the day on Monday,” the letter states.

There was no ammunition, Thomason said in the letter.
