Six high school students were suspended from school Tuesday and sent home for the remainder of the school day, after an investigation into an inappropriate e-mail. Douglas County Sheriff’s deputies were called in to help with the investigation.

The e-mail was sent Monday to some students and faculty at Concordia Jr.-Sr. High School at 156th and Fort Streets. The e-mail contained content that could be interpreted as a potential security threat. As a result of the investigation, six Concordia High School students were suspended from school Tuesday.
