WARRENSVILLE HEIGHTS, Ohio -- A Warrensville Heights High School student was arrested Wednesday morning when security officers caught him taking a gun into the building, officials said.

The gun set off the building's metal detectors about 8:20 a.m. Security officers confiscated it and called police, who came to the high school and arrested the student, Warrensville Heights City School District spokeswoman Kendra Davis said.

No one was harmed in the incident.

It's unclear why the gun was taken to the school, Davis said. The incident remains under investigation.

The student could also face school discipline once the criminal investigation is completed, Davis said.

Davis could not provide the student's age or grade. She also could not say if he has any disciplinary history.

"Our scholars' safety is our top priority and we have measures in place, such as metal detectors, to keep the high school and our other educational facilities secure," Warrensville Heights City School District Superintendent Donald J. Jolly II said in a statement.
