Garner Magnet High School went on code red lockdown shortly before noon Friday.
Garner Police Department said it received a report of a student with a gun on campus. The student reportedly ran into the woods near the school before surrendering to officers.
The school went into lockdown because of the threat.
Police said the student in question has cooperated with investigators and no weapon has been found.
Lockdowns and emergencies at schools in central North Carolina have been the norm this week.
On Friday, Orange County Schools increased security to due threats on social media. No credible threat was found.
A different social media threat to 40 different schools in the state caused law enforcement to scramble to investigate. Cary Elementary School was locked down in this investigation. Ultimately, those threats turned out to be unfounded.
A pepper spray incident at Smithfield-Selma High School injured multiple students. Then, the next day a report of a gun on campus forced a precautionary lockdown; no gun was ever located.
