Sanderson High School went on a Code Red lockdown Monday afternoon because of a reported intruder on campus.
In a message posted after the school lifted the Code Red, principal Gregory Decker said a caller phoned the Raleigh school about an intruder on campus. "Authorities arrived immediately, checked our campus and determined there was no intruder on campus," he said. "The lockdown lasted about 40 minutes."
"Code Red" means an immediate threat to the school. Students move into safe areas, and all interior doors are locked.
Decker came on the intercom about 1:50 p.m. Monday and said "Code Red" multiple times, one student said in a phone call with a parent.
Students in the east building on the Raleigh campus said they could hear someone going door to door banging or kicking on the locked classroom doors, the student said. Decker later came on and said, "No one leave your classroom," the student said.
About 2:20 p.m., the school cleared students to leave, the student said.
Parents reported multiple police cars in the school parking lot.
Wake County Commissioner John Burns, whose son attends Sanderson High, called for stronger gun control in a Twitter post on Monday.
"I do not want to continue to pretend it is normal to be a society where I am proud of my son for directing his classmates into a nearby bathroom and manning the door because of a Code Red," Burns wrote. "Either we do something real about guns or we abandon all claims to being civilized. #enough."
Later this month, Sanderson High is scheduled to host an N.C. Town Hall on School Safety. Organizers are calling it a "community conversation about gun violence and the safety of children in our schools."
The town hall is scheduled for 6:30 p.m. May 29 in the school's auditorium.
Panelists include State Sens. John Alexander and Jay Chaudhuri, Wake County school board chairwoman Monika Johnson-Hostler and the school system's security chief Russ Smith.
