ROCK HILL — A 15-year-old South Pointe High School student was arrested Tuesday after school officials learned he brought a butterfly knife onto school grounds.

Around 12:15 p.m., the school’s assistant principal received information that the boy, a Rock Hill resident, had a knife, according to a Rock Hill police report.

The assistant principal met with the student and found the knife, the report states. The school’s resource officer was called and charged the boy with carrying a weapon on school property.

The report did not say where he stashed the knife.

He was released to his father. School officials kept the knife for discipline hearings.
