An officer who got suspicious at a Knox County School ended up finding a gun on a man on campus.
Knoxville police say a school resource officer saw 18-year-old Jonathan Scales smoking a cigarette outside Central High School's office on Thursday.
The officer asked to see an ID. When Scales couldn't give them one, police say he got squirrely and ran away.
Two officers arrested him after a brief struggle; neither were injured. They searched the suspect and found a loaded revolver in his backpack.
Police say Scales is not a student. They say he was waiting for a student at the school.
He faces charges for assault, resisting arrest, and possession of a weapon on school property.
