Four students have been injured in a shooting at Madison Junior/Senior High School in Middletown, Ohio, on Monday, after a 14-year-old allegedly opened fired in the lunchroom. None of the injuries are life-threatening.

According to the Associated Press, Butler County Sheriff Richard Jones said that the suspect, who was apprehended with the the help of a police dog, was a student. Jones also said that there was a motive to the shooting, but he did not identify that motive.

The suspect opened fire around 11:30 am on Monday morning. Then, ABC News reports, he ran outside, dropped his gun, and was apprehended while still on school grounds.

Madison is a small school, with about 250 junior high and 500 high school students. From the AP:

Afterward, classmates described a chaotic scene where they weren’t sure what was happening at first.

Thirteen-year-old Shelby Kinnin said she heard “a couple of bangs” and realized she was near the shooter.

“I didn’t really know it was gunshots until I looked over and a kid was grabbing his leg and falling over,” she said.

Many people ran from the scene, and the shooter went out a door, she said. She recognized him as a boy who was in a class with her last year, though she wasn’t sure of his name.

The suspect, who ABC reports has been interviewed by investigators and is being held in a juvenile detention facility, was charged as a juvenile with two counts of attempted murder, two counts of felonious assault, one count of inducing panic, and one count of making terrorist threats. Jones said authorities have not yet determined how he acquired a gun.
