Questions over man arrested at LAX with bulletproof vest, body bags Authorities are not sure why a man flying into the U.S. from Asia was wearing a bulletproof vest and had body bags and weapons in his luggage. Officials are also trying to find out how the weapons got through security. The man has been charged with transporting dangerous materials, federal authorities said Tuesday. As if the gear allegedly worn by Yongda Huang Harris wasn't alarming enough, authorities say he was also transporting assorted weapons, biohazard suits and body bags in his carry-on luggage. Harris, 28, was arrested Friday and is expected to make his initial appearance in U.S. District Court in Los Angeles on Tuesday afternoon. He is charged with one count of transporting hazardous materials with a possible maximum sentence of up to five years in prison. DOCUMENT: Man arrested at LAX for transporting hazardous materials A resident of Boston, Harris was due to fly home after arriving at LAX from Japan. But U.S. Customs and Border Protection officers observed his unusual choice in clothing and immediately referred him for secondary inspection. The search turned up items that in addition to the body bags and biohazard suits included a pyrotechnic smoke grenade, three leather-coated billy clubs, a collapsible baton, a full-face respirator, various knives, a hatchet, handcuffs, leg irons and a device to repel dogs, authorities said. According to a federal affidavit, the Los Angeles Police Department's bomb squad X-rayed the smoke grenade and determined that it was a prohibited device because it could fill the cabin of an airplane with smoke or cause a fire.
