A bomb threat disrupted school at Sandy Hook Elementary School six years ago to the day of the mass shooting that killed 26 faculty members and schoolchildren. The Newtown, Connecticut elementary school evacuated and sent students home for the day after someone called in the bomb threat, according to NBC News.

The threat was called in around 9 a.m. ET on Friday and police were sent to Sandy Hook Elementary to investigate. Crucially, no bombs or other dangers were found and police said the threat was likely nothing to worry about.

Still, the school week ended early for the students at Sandy Hook due to the threat. The threat and disruption occurred on the sixth anniversary of Adam Lanza killing more than two dozen students and teachers at the school.

A series of bomb threats were made across North America this week, though none came to fruition. The threats were made to public places like hospitals and schools, including the Bronx High School of Science in New York City on Thursday. Students were evacuated after the threat was made.
