ATLANTA (AP) — After a man aimed a rifle at a school bus and dropped a notebook that listed bus numbers, police in an Atlanta suburb are escorting school buses and guarding students at bus stops.

The man fled when witnesses confronted him Monday morning, but police recovered the rifle and notebook he dropped at the scene, just south of Atlanta.

Clayton County police Officer Phong Nguyen says a witness saw the man pointing the rifle at a passing school bus.

County school officials said another witness chased the man but stopped when the suspect fired a second gun at him.

Schools spokesman David Waller says police are shadowing buses from six schools. He says the notebook was found with the weapon.
