The Davidson County School system added an extra school resource officer at North Davidson High School on Friday in response to a threat posted on social media, according to a statement from the school system.

In the written statement, Davidson County Schools spokeswoman Donna Stafford said administrators were investigating an alleged threat toward the school and had taken precautions, although they have not found any evidence to confirm the rumor.

“All reports made to the Davidson County School system are taken seriously and thoroughly investigated by school officials and the sheriff's department,” the statement read. “Due to reports of inappropriate remarks on social media we are actively monitoring North Davidson High School with additional staff on site. Although our investigation into this matter remains ongoing, at this point in our investigation we have yet to identify an actual credible threat towards the school. Safety is our top concern and we will continue to observe NDHS throughout the day.”

Sources with the Davidson County Sheriff’s Office stated due to rumors of possible altercations, an extra school resource officer was posted at the school Friday.

A thread on a social media site showed a discussion stating a student had threatened to “shoot up” the school on Friday in retaliation for an altercation that had occurred during the annual water balloon fight earlier in the week. The rumor has continued on multiple platforms of social media, inciting concern from parents of students at North Davidson High School.

Officials with the Sheriff's Office said they had no reports of any disruptions at the school on Friday.
