CHATTANOOGA (WRCB) - The assistant principal at Chattanooga's Central High School found a .38 caliber handgun and five bullets in a student's backpack on Monday.

According to an email to Channel 3 Eyewitness News from the Sheriff's Office, the administrator was acting on a tip that the student possibly had alcohol with him at school. The student was searched. No alcohol was found but the assistant principal did find the gun. It was unloaded and wrapped in a towel. The five rounds of ammunition were with it. 

A School Resource Officer with the Hamilton County Sheriff's Office was called in to help. He arrested the 17-year-old boy and took him to the Hamilton County Juvenile Detention Center.
