The lockdown on Wednesday at Norwich City Schools was done out of an abundance of caution as police hunted for a suspect in a Route 12 crime. Superintendent Scott Ryan said while the search was underway a staff member saw an unidentifiable non-school aged man fraternizing with students at both the High School and Middle School during arrival, close to the entry doors. The lockdown was lifted after district officials received confirmation from Norwich Police that it was safe to do so.
