Huntsville City School officials say students handling a firearm in a restroom this morning discharged the weapon.

No one was reportedly injured.

The incident happened about 8:45 a.m. at McDonnell Elementary, according to a statement by the system. There was no word on how many students were involved in the incident, which apparently involved students handling a firearm and ammunition.

“The students’ teacher and school administration responded immediately to the disturbance caused by the discharge of the firearm,” the system said in a statement.

Administrators contacted the parents and guardians of the students involved, and will begin disciplinary procedures according to the system’s policies. There will also be an investigation into how students were able to bring the weapon onto campus, school officials said.

“Please ensure that all weapons in your home are secured and that your students do not have access to them,” a statement reads. “The school is safe and conducted its typical school activities, and we commend the faculty, staff, and administration for their fast response.”

Earlier this year, a fourth-grader was wounded after accidentally firing a weapon at Sonnie Hereford Elementary.
