CHARLOTTE, N.C. -- Charlotte-Mecklenburg Schools is investigating after two students were found to be in possession of weapons on an elementary school campus.

On Thursday, a staff member found two students to be in possession of a gun and a box cutter, respectively, on the campus of Huntingtowne Farms Elementary School in Charlotte's Quail Hollow neighborhood.

"My heart completely dropped," said Selena St. Juste, a concerned parent. "We get those type of phone calls if there's a reminder or if there's a day off of school or picture day is coming, but hearing that was really scary."Police were called and the students are being disciplined. Still, some parents are uneasy hearing the news.

"My son is in kindergarten and I've never had this happen before," said Krystal Frazier, a concerned parent.

Frazier got the principal's message on her phone. Her initial thoughts were was anyone in grave danger.

"I was just trying to make sure the kids were safe and my son was safe as well," said Frazier.

Last school year there were 322 cases of weapons on CMS campuses which includes guns and knives.

The CMS school district released this statement about Thursday's incident saying in part:

"Any student found to have brought weapons on campus will be disciplined as outlined in the Code of Student Conduct."
