GWINNETT COUNTY, Ga. -- An altercation in front of Norcross High School put the school in a hard lockdown on Thursday.
At about 10:30 Thursday morning, dispatchers received a call regarding a fight in progress on the side of the school building.
When officers arrived, the fight -- which involved people who were not students at the high school -- ended.
First responders transported one person to a local hospital for treatment.
Another suspect blended into the students in the school.
Authorities said officers searched each classroom until they were able to determine who was present who not supposed to be. The suspect was found in an empty room and taken into custody. The lockdown was lifted just after 1 p.m.
Some parents were upset by what transpired.
"We're not going to leave until we get our children out of there," one parent said while standing outside.
In the end, the school day continued for some students, while others, whose parents came to get them, got an early day off.
One person, a former student at the school, is in custody.
