Authorities at an international airport in Hawaii arrested a traveler from Japan for "terroristic threatening" after he allegedly brought two hand grenades in his carry-on luggage.

The Hawaii Police Department and the Transportation Security Administration (TSA) confirmed to Fox News Digital that Hilo International Airport was evacuated Tuesday after officials discovered two items resembling grenades during X-ray screening.

Police said Akito Fukushima of Kanazawa, Japan, was arrested for first-degree terroristic threatening after the incident.
