A 12-year-old boy is in police custody in Ewa Beach, Hawaii, after allegedly pulling a gun on a 13-year-old girl near three schools. No one was hurt, but the incident has rattled parents.

• The boy allegedly threatened to shoot the girl's brother in the morning along Fort Weaver Road, near Campbell High, Ilima Intermediate, and Pohakea Elementary.
• School staff later found the gun in his backpack, and Honolulu police arrested him on campus.
• He faces suspicion of terroristic threatening and a firearm offense.
• All three nearby schools sent letters home asking parents to lock up dangerous items and talk to their kids about weapons at school.
• Bringing a weapon to school is a class A offense, and any student caught will be expelled.

Outlook: The boy remains in custody, and schools in the area will likely tighten security checks and messaging to families in the coming days.
