OMAHA, Neb. (AP) — A 12-year-old Omaha boy has been arrested, accused of bringing an unloaded gun to his school following an argument.

Omaha police say the arrest was made Thursday afternoon after officers learned that a school resource officer was detaining the boy and had secured the weapon.

Investigators say that after the argument, the boy left and returned to the school with the gun.

The 12-year-old was arrested on suspicion of having a firearm on school property and other weapons-related counts.

The Associated Press generally does not name juveniles accused of crimes.
