Just days into the start of the new school year, a Norwalk elementary school was placed on lockdown for almost an hour after a teacher heard what he or she thought were gunshots from outside the school.
Nothing was found and the lockdown was lifted as of 12:20 p.m.
Police said they received the report of possible shots fired at 11:25 a.m. and responded to Cranbury Elementary School, which was placed in lockdown as a precaution.
Two officers were in the immediate vicinity and did not find anything suspicious, police said.
Officers checked the area, as well as the trails at Cranbury Park, and received no other reports of shots. Nothing suspiicous was located, police said.
Police have not identified the source of the noise, but said construction is happening nearby.
Police have continued to monitor the area and have maintained a presence at the school to assauge fears or security concerns.
Police Chief Thomas Kulhawik said the school responded appropriately to the suspected emergency.
