A false alarm set off a lockdown at a Honolulu high school, but police found no real danger.

• A phone system glitch triggered a safety alert at Farrington High School.
• Police responded and checked both the school and nearby campuses as a precaution.
• Officers confirmed there was no active threat.
• The lockdown was lifted shortly after.

Outlook: No ongoing danger; officials will likely review why the alert system misfired.
