It happened in New York City. The boy allegedly followed the girl into a subway station, pointed a gun at her head and demanded a McNugget again, police said. The girl smacked the gun away from her head and told the boy to leave her alone.
She boarded the train unharmed, according to police. The girl later saw the boy showing the gun to another child on the train.
Police took the boy into custody Wednesday, after the girl reported the incident to school officials.
