CHARDON, Ohio - A gunman opened fire inside a high school cafeteria at the start of the school day Monday, wounding five students, one of whom later died, authorities said. A suspect — believed to be a student — was arrested a short distance away.

The suspect was taken into custody near his car about half a mile from the suburban Cleveland school, said FBI agent Vicki Anderson. The Geauga County Sheriff's Office said that the suspect turned himself in after being chased out of the school by a teacher, CBS News reports.

At a news conference announcing the victim's death, Chardon Police Chief Timothy McKenna said the suspect hasn't been charged and his name isn't being released because he is a juvenile.

FBI agent Scott Wilson would not comment on a possible motive for the attack.

The handgun allegedly used in the attack has been recovered and is now in the custody of the Bureau of Alcohol, Tobacco, Firearms and Explosives, where authorities are running a background trace on the weapon to determine its origin and ownership, reports Bob Orr.

There is no word yet on the number of shots fired or the caliber of the bullet.

The sheriff's office identified the victims as four male students and one female student. Earlier, CBS affiliate WOIO-TV in Cleveland reported on air that a 17-year-old boy was listed in serious condition and an 18-year-old woman was in stable condition at the Cleveland Clinic's Hillcrest Hospital in suburban Cleveland.

Students screamed and ran in panic through the halls when gunfire broke out around 7:30 a.m. at the 1,100-student Chardon High School.

Freshman Danny Komertz, 15, said it appeared the gunman was targeting a group of students sitting at a cafeteria table. The shooter was known as an outcast who had apparently been bullied, Komertz said.

Komertz was just about to leave for his first-period health class when he heard a loud popping sound and then saw the gunman open fire, he said. The student who was killed was trying to get under a table to protect himself and shield his face, Komertz said. At least 100 students were in the cafeteria at the time.

Heather Ziska, 17, said she was in the cafeteria when she and other students heard popping noises in the hall. She said she saw a boy she recognized as a fellow student come into the cafeteria and start shooting.

She said she and several others immediately ran outside, while other friends ran into a middle school and others locked themselves in a teachers' lounge.

"Everybody just started running," said 17-year-old Megan Hennessy, who was in class when she heard loud noises. "Everyone was running and screaming down the hallway."

Television news footage showed anxious parents escorting children away from a school building, and ambulances could be seen outside.

A spokeswoman for Cleveland's MetroHealth System said a medical helicopter was dispatched to the high school. The sheriff's office said that two students were taken to Hillcrest Hospital and an additional three students were taken to Cleveland's MetroHealth Medical Center, CBS News reports.

Students at the high school and a middle school had already started their day when the shooting happened, but bus runs for elementary school children were stopped. All classes in the district were canceled.

Parents of high school students were told to go to an elementary school to pick up their children.

Chardon, a city of about 5,100 people, is about 30 miles east of Cleveland.
