Police asked Edinburgh schools to place its three buildings on lockdown for about one hour on Thursday.
The school district received the request from the Edinburgh Police Department about 9 a.m., and during the lockdown students weren't allowed to leave their classrooms. The lockdown was over by about 10 a.m., Superintendent William Glentzer said.
Glentzer referred all questions about why police asked for the lockdown to the Edinburgh Police Department, who could not be reached for comment. Nothing dangerous was happening inside any of Edinburgh's schools, Glentzer said. Parents also received a call from the school district about the lockdown, Glentzer said.
"Once we get notification, we do the best we can to protect our kids. That's our job," Glentzer said.
