Parents in Vance County reached out to ABC11 Friday after their children saw posts on social media sites about threats of violence Friday.
Concerns escalated when graffiti was found on buses and windows at Northern Vance High School.
It was removed, but the incidents prompted school officials in Vance County to send out a recorded call to parents explaining the situation.
Terri Hedrick, the public information office for Vance Schools, said "everything is fine," at Northern and at Southern Vance High School.
There was also extra law enforcement at the schools as a precaution.
School officials told ABC11 that the social media threats were disrupting the school day.
It also prompted some parents to take their children out of school early.
There were also some reports of students at South Granville High School getting threatening text messages, according to Granville County School officials.
The high school went in to lockdown as a precaution, but that has since been lifted. The Granville County Sheriff's Office and Creedmoor Police were also called to the school and will stay on campus until dismissal. School officials cancelled all after-school activities for Friday.
Officials said they are trying to figure out the source for the messages, but stress that there have been no incidents at either school.
