Operations at Hawaii’s Hilo International Airport were halted when security screeners spotted two items that looked like grenades in a bag belonging to a man from Japan. Police say officers evacuated the terminal area Tuesday morning. A bomb squad determined the grenades were inert, and airport operations resumed about an hour later. Police arrested a 41-year-old man from Kanazawa, Japan, on suspicion of first-degree terroristic threatening. Police say he was taken to an east Hawaii detention facility and then released pending investigation.
