Four students were injured and one gunman is in custody following a shooting this morning at Chardon High School in Ohio, according to ABC News' Cleveland affiliate WEWS.
Two students were taken by helicopter to Hillcrest Hospital and two were taken to MetroHealth Hospital, according to WEWS.
The station cited the FBI while reporting that a gunman was in custody.
"We are on scene and can confirm that a SWAT team is out there, making things secure and, of course, conducting the preliminary steps of the invesitgation with the local authorities that called us," Vicki Anderson, a spokeswoman for the FBI's Cleveland division, told ABCNews.com.
The Chardon Fire Department was called to the school at about 7:45 a.m. in response to a report of "several people shot," according to Inspector William Crowley of the Chardon Fire Department.
Multiple law enforcement agencies are on-scene, including a SWAT team that is checking the entire school.
The superintendent immediately canceled classes at all schools in the district. Students who were still on school buses were being dropped back off at their homes and parents were called to pick up their children that were already at school.
The Chardon School District sent a voicemail to parents that schools are closed and high school students are being moved to the middle school, according to WEWS.
Chardon is a village in Geauga County, about 35 miles west of Cleveland, Ohio.
