Everyone’s OK and things are back to normal at Niles High School after the building was put on lockdown Monday. The administration sent a letter out to parents telling them the place was put on lockdown shortly before 11 a.m. when an airsoft gun was found in a student’s backpack. That student has since been caught. Airsoft guns shoot plastic pellets, but can resemble real guns. The high school principal says no threat was made and no one was in any danger. The school says it’s working with police on the matter.
