Students at Sandy Hook Elementary School in Connecticut were sent home Friday morning after Newton Police Department received a call around 9 a.m. EST about a possible bomb threat, according to NBC News. Friday also marked six years since lone gunman Adam Lanza entered the school and murdered 26 students and teachers.

Following the call, authorities were on-site at the school to search the grounds. While law enforcement did not find any credible threat, students were sent home for the remainder of the day as a safety precaution. Newtown police Lt. Aaron Bahamonde believes an increased level of angst around town on the fatal anniversary led the Sandy Hook superintendent to cancel all remaining classes, writes ABC News.

ABC News also notes before the alleged bomb threat, school administrators and students held a moment of silence Friday morning to remember the December 2012 victims. Lanza also shot and killed his mother before taking the lives of Sandy Hook students and faculty.
