We updated this story here on Wednesday night.
Update at 10:02 a.m. March 13:
The precautionary lockdown at Andrew Avenue School has been lifted, according to police.
In a statement just released, Lt. Bryan Cammarata, a Naugatuck Police Spokesman, reinforced that there was no threat to the school itself. The lockdown was precautionary in nature, given the school's proximity to the area where the reported gunfire came from — the nearby woods.
Police will maintain a presence at the elementary school for the remainder of the day, Cammarata said.
The original report follows:
Andrew Avenue School in Naugatuck is in lockdown this morning after police received calls reporting gunfire in the area.
Lt. Bryan Cammarata, a Naugatuck Police Spokesman, said a sweep of the elementary school building and school grounds has been completed and that no shooter was found. The school is still in lockdown as of 9:45 a.m., he said.
The school is located at the base of Andrew Mountain, a wooded area that Cammarata said is frequented by hunters. Police are looking into that as a possible explanation for the gunfire.
The first report of gun shots came in at 8:55 a.m., Cammarata said.
A police officer will remain at the school for the rest of the day as a precaution.
Naugatuck Patch will update this article as more information becomes available.
