A hand grenade found in a carry-on bag at Los Angeles International Airport prompted officials to delay five flights and disrupt travel plans for some 800 passengers for a couple of hours, according to the Transportation Security Administration.  Officials arrested one person in relation to the incident, according to a TSA statement on Friday. It was not immediately clear when the incident occurred. “The Terminal 1 checkpoint was closed while the Explosive Ordnance Disposal team transported the grenade to an offsite location to be disrupted,” the statement added. “Five flights were delayed 2 hours, 19 minutes, affecting 800 passengers.” More
