Police are looking for the person who called in a threat that prompted Wednesday's evacuation of the school being used by the students and staff at Sandy Hook Elementary School.

Police were called to the school at around 9:30 a.m., a little more than an hour after the school day began.

Sandy Hook Elementary students have been attending classes at the temporary location in Monroe since the tragic shootings at the old Sandy Hook Elementary School claimed the lives of 20 students and six teachers back in December 2012.

Students were dismissed and taken to a nearby school.

Police say authorities conducted a thorough search of the building and grounds, but no sign of a threat was found.

Newtown residents say they are hurt that something like this even happened, but say the tight-knit community has grown stronger since the tragic shooting. They say after the hoax, their message of Newtown Strong still stands firm.

Newtown officials say school will be back in session on Thursday. Police are still investigating the call.
