WAKE FOREST — Extra police will be at Wake Forest-Rolesville High School on Friday as a precautionary response to a report that students will bring weapons to campus that day.

In a letter sent home to families Wednesday and posted on the school website, Wake Forest-Rolesville High Principal Patti Hamler said that a rumor has been circulating that some students plan to bring weapons to campus Friday. In the letter, Hamler cited “recent national events” and stated that the school takes any threat or rumor of violence seriously.

Schools around the country have been on a heightened state of alert since a gunman killed 20 children and six adults at Sandy Hook Elementary School in Newtown, Conn., Friday.

Hamler said in the letter that school administrators and Wake County schools security staff “have no reason to believe there is any real threat to student safety.”

But as a precaution, Hamler said the school resource officer, Wake County schools security and additional Wake Forest police officers will be on campus Friday “to closely monitor student activity and to ensure safety.”

“We encourage you to talk with your teens to reassure them that our schools are safe, and remind them how important it is to immediately inform school staff if they ever have any security concerns,” Hamler says in the letter. “We encourage students to report any suspicious activity or discussion of violence right away.”
