Authorities in Moore say an elementary school is on lockdown after a teacher found a loaded gun in his classroom.
Moore Police Department spokesman Jeremy Lewis says students at Plaza Tower Elementary School are not in any danger. Lewis tells Oklahoma City television station KWTV (http://is.gd/gg0o4A ) that police are now searching the building to make sure there are no more weapons.
Police say the teacher found the handgun in his chair when he arrived at work Monday morning. Students who were already at the school were taken to the cafeteria, while parents who were dropping off their children were turned away.
Lewis says there was a substitute teacher in the classroom Friday and police are trying to determine whether that teacher had any information about the gun.
