Four students were wounded Monday morning at Chardon High School in Chardon, Ohio, and local news channels said there's only one gunman.

Joseph Bergant II, Chardon Local Schools superintendent, told Fox 8 News in Cleveland that the suspect was a lone gunman, and has been taken into police custody.

The conditions of the injured students have not yet been released. Local news said the shooting occurred in the cafeteria and three boys and one girl were hit by five shots.

The Chardon Police Department was at the scene and a medical helicopter was sent to the scene. Chardon is about 30 miles east of Cleveland.

All classes in schools across the district had been canceled. Chardon Local Schools' community coordinator Ellen Ondrey said the school was in "crisis mode."

She said students at the high school and middle school had already started their day and bus runs for elementary school kids were stopped.

The deadliest high school shooting in U.S. history occurred in 1999 at Columbine High School in Colorado, where two senior students killed 12 students and one teacher. The pair then committed suicide.
