Extra security is surrounding a suburban school Monday morning after a bomb threat was discovered.
The threat was found on an exterior wall at Oakwood School in Lemont.
The message said that the school would be bombed on Tuesday.
Classes remain on schedule, as parents were told about this in an e-mail Sunday night.
No arrests have been made.
Police say this isn’t a credible threat, but they still plan to sweep the building and watch the hallways.
They may also check bags that are brought inside.
River Valley School, which shares the same campus, is also getting more security.
