CANTON, Ga. -- One teenager is in custody, another is stable and recovering after a stabbing at Woodstock High School.

Cherokee County Sheriff Frank Reynolds said a fight between two 16-year-old male students broke out in the bathroom and spilled out into the hallway.

A teenager dressed in a black pants and black shirt stabbed another student in the neck and chest. Witnesses say the injured student was bleeding heavily in the 300 hallway near the Family and Consumer Sciences room.

"It was a very scary situation for everybody for a while there," one student told 11Alive.

When the call for help went out, a nurse was already helping the injured student. The armed classmate was on the run.

Cell phone video from inside the school shows armed officers going from classroom searching for the suspect. Lt. Jay Backer with the Cherokee Co. Sheriff's Office said that suspect is now custody. He was found near his home. The subdivision backs up to a wooded area between the homes and the school.

In a message to parents, the school system said, "Do not report to the school! All doors are locked and no one is allowed in or out of the building. Parents will not be permitted to pick up students until the Code Red is lifted. We understand that this is a stressful message, but please know that the safety and security of all students is our priority."

The injured student was transported in stable condition.

After nearly two hours in lockdown, students were dismissed on time at 3:15 p.m., creating gridlock on campus.

While the injured student is expected to recover, the other could be charged as an adult."
