Maui High School and the nearby Kahului Elementary School were placed on lockdown for about an hour Monday, after witnesses said they saw a man carrying what looked like a hand gun on the high school campus, Police Lt. Wayne Ibarra said.

Ibarra said police searched both school campuses and found no sign of the suspect.

In a press release the Maui Police Department said it got a 911 call at about 10:47 a.m., “from an anonymous female caller, reporting that she observed a 16-year-old male, thin built, about 5’3” tall, with medium length wavy hair, wearing a white shirt and jeans, to be concealing a black handgun under his shirt and going into the Maui High School Campus by jumping over the fence near the Banana Patch area off of Papa Avenue.”

The lockdown began shortly before 11:15 and ended at 12:30 p.m.
