Two middle school students are in custody in Delaware today after a gun is fired inside of a school restroom. No one was injured in the shooting.

Police say officers were called to Central Middle School in Dover, Delaware about 12:15 p.m. on Tuesday. Allegedly, one student brought a gun to the school and may have given it to another student. Police did not describe the weapon that went off in the school bathroom.

Police do not know if the weapon was fired intentionally, but they have confirmed that the incident was not related to a bomb threat made toward the school earlier that day.

The school’s website says classes have resumed since the school was put on lockdown after the shooting, but after-school and evening activities are cancelled.
