RAVENNA, Ohio -- Ravenna schools were placed on lockdown for about 30 minutes on Thursday morning after an elementary school staff member spotted a person with a gun walking on Main Street, according to the school district.

The staff member at West Main Elementary School called 911 to tell the school resource officer and police department about the armed person, the school district said in a statement.

West Main went into a “full lockdown” and all other school buildings were put on a “soft lockdown." The statement did not indicate what constitutes a “soft lockdown.”

Within 30 minutes, Ravenna police apprehended the person, the district said. Ravenna police have not released any information about the incident.

The school district said its “see something, say something” policy was effective in keeping students safe.
