Dexter Community Schools issued a lockdown for its six schools on Tuesday following a report of "shots fired" near the apartment complex off of Dan Hoey Road.
The report came in at 2:45 p.m., according to Sgt. Beth Gieske, of the Washtenaw County Sheriff's Office.
According to a telephone alert issued by Superintendent Mary Marshall, building teachers reported "suspicious noises" emanating from the apartment complex, which is located near and elementary schools.
"There were several unidentified noises that caused us to issue a lockdown in order to give the Washtenaw County Sheriff's Office time to investigate," Marshall said. "When you don't know, it's better to err on the side of locking down (the schools)."
At 2:54 p.m., sheriff's deputies determined the school could safely dismiss students, Marshall said.
"We've been informed by the sheriff that we can release the lockdown status and plan for dismissal as usual. Deputies are currently investigating the source of the complaining noises," she said.
This is the second week in a row unidentifable noises caused school district officials to activate an emergency lockdown. Last week, forced officials to issue a lockdown as students were being dismissed for the school day.
