A student was shot and injured at a North Carolina high school Monday morning

A Butler High School student is undergoing surgery following a shooting that took place early Monday morning. The resulting shutdown of the school has been lifted.

Officials said the sole injured student is in critical condition according to WSOC TV. Police also took a second student into custody and now advise that the threat is over.

Clayton Wilcox, the Charlotte-Mecklenburg Schools (CMS) Superintendent, identified a reason for the horrific incident. He said the shooter was angry at the victim, leading to the attack in the main hallway.

"The student who was shot is in surgery at this time so I don't have any comment on his condition, other than to say, we're incredibly sad, and we're sorry for this family. But we're also sorry for the young person who thought the only way to solve this problem was with a gun."

The Matthew Police Department released a statement on their Facebook page saying the affected student has "unknown injuries at this time."

"This is believed to be an isolated incident and the scene has now been secured by police."

CMS officials added that officers apprehended the shooter in a classroom. They now have the weapon in law enforcement's possession.

Police called parents with the initial alert. The parents were later directed to congregate at the Elevation Church located on East Independence Boulevard.

As concern grew, they flocked to the school of 2,000 pupils to find their kids at minutes to 9 a.m. They desperately waited outside the roped off area and hugged each other in comfort.

Around 9:15 a.m, after the student was rushed to the hospital and the suspect taken into custody, the shutdown lifted. Classes are to go on as normally scheduled.

The names of the two students involved in the situation remain unknown to the wider public. Police will continue to investigate.

This incident follows a recent shooting that took place in Louisville Kentucky last Wednesday.

Two people received fatal injuries from a gunman who walked into a Jeffersontown Kroger store at 3 p.m. A grandfather shopping inside with his grandson, and a woman in the parking lot died at the scene.

Police soon apprehended the man in a parking lot located nearby. They later identified him as Gregory Alan Bush, 51. He was charged with two counts of murder and over 10 counts of wanton endangerment.

Officials believe the gunman randomly selected his victims. One shopper named Eric Deacon intended to assist the lady outside. He said:

"Once they got the gentleman on the ground, I hollered at them and said, 'Look, I'm an EMT. Let me get out here and try to help this woman.' So that’s when I went, ran over, I get down. I’m getting ready to start CPR on her, and when I looked at her, I knew she was gone. There was nothing I could do."

The Kroger establishment closed down following the incident. A spokesperson said it "will reopen after the investigation concludes." No motive has been found thus far.
